Trying to factor by splitting the middle term
2.1 Factoring 8x2-6x-3
The first term is, 8x2 its coefficient is 8 .
The middle term is, -6x its coefficient is -6 .
The last term, "the constant", is -3
Step-1 : Multiply the coefficient of the first term by the constant 8 • -3 = -24
Step-2 : Find two factors of -24 whose sum equals the coefficient of the middle term, which is -6 .
-24 + 1 = -23
-12 + 2 = -10
-8 + 3 = -5
-6 + 4 = -2
-4 + 6 = 2
-3 + 8 = 5
-2 + 12 = 10
-1 + 24 = 23
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
8x2 - 6x - 3

1) Find the value of 1 + 3x when x = 1
Answer:
4
Step-by-step explanation:
So, since we already know x = 1, we just need to figure out what 3 x 1 is. (Since there's no space between the 3 and the x, 3x would be 3 times x.)
3 x 1 = 3.
So, our "new equation" is:
1 + 3
Add them together to find the answer:
1 + 3 = 4
4 is your answer.
Hope this helps and have a nice day!

Find the value of x in the triangle shown below
Answer:
x = 62
Step-by-step explanation:
The triangle is isosceles. That means two sides are equal. The angles opposite those equal sides are also equal.
Every triangle has 180 degrees.
The unmarked angle is also x.
x + x + 56 = 180 Combine the left
2x + 56 = 180 Subtract 56 from both sides
2x = 180 - 56
2x = 124 Divide by 2
2x/2 = 124/2
x = 62
how many feet of border will I need to put around the 4 side my bulletin board if the length if 5 yards and the width is 2 yards
Is an Angle Two or 1 dimensional ?
Answer:
An ordinary angle is a measure of the length subtended by a one-dimensional subset of the plane. For example, an angle of 60∘ is subtended from a point by a 16 portion of a circle centered at that point. The 16 arc that subtends the angle is a one-dimensional subset of the two-dimensional plane.
Step-by-step explanation:
The polygons are similar Find the value of x
Answer:
The value of the x variable is 30.
Step-by-step explanation:
Since the triangles are similar, the corresponding sides of both triangles have a common ratio. The 18:12 ratio of side LK and QR is equal to 2:3, and the 21:14 ratio of sides JL and PQ is also equal to 2:3. Based on this, we know that 2/3 * x = 20, so we isolate the x variable by dividing both sides of the equation by 2/3 to get the answer: x = 30.
Please help, What is the slope of the line???
Answer:
Step-by-step explanation:
The slope is calculated using rise over run, or y2-x2/y1-x1
The clear coordinates are (-3, 2) and (1,4).
Let 4 be y2, 1 be x2, 2 be y1 and -3 be x1.

The sum of two numbers is 13 and the difference is 5.
Whats the answer?
Answer: the first number is 9, the second is 4
Step-by-step explanation:
let n = 1st number
let n-5 = 2nd number
n+(n-5)=13
collect like terms: 2n-5=13
add 5 to both sides
2n=18
divide both sides by 2
n=9
n-5=4
George makes $20 doing lawn work for 4 hours each
week. He wants to buy a $2,500 used car from his
grandmother. He has been saving this money for
30 weeks. How much has he saved?
Answer:
$600
Step-by-step explanation:
1 week = $20
30 weeks = 20 x 30 = $ 600
The saving of 30 weeks would be an amount of 600 dollars.
What is the Multiplication operation?In mathematics, Multiplication operations perform Multiplying values on either side of the operator.
For example 4×2 = 8
George makes $20 doing lawn work for 4 hours each week.
He has been saving this money for 30 weeks
The saving of one week = $20
The saving of 30 weeks = $20 × 30
Apply the multiplication operation to get
The saving of 30 weeks = $600
Alternative method :
According to the given situation, we can write a ratio as
one week : 20 dollars = 30 weeks : x dollars
⇒ 1 / 20 = 30 / x
Apply the cross-multiplication operation,
⇒ 1 × x = 30 × 20
Apply the multiplication operation to get
⇒ x = 600
Hence, the saving of 30 weeks would be an amount of 600 dollars.

The following points lies on a Given line (10,0) and (0,-15) who’ve of the following points will also Be on the given line
(10,5) b(-3-15) c (1,-13.5). D(12,5)
Answer:
Step-by-step explanation:
We can form an equation from the two given points.
The standard form of an equation for a straight line is y=mx+b, where m is the slope and b is the y-intercept (the value of y when x = 0).
We can calculate the slope from the two given points, (10,0) and (0,-15). Slope is Rise/Run, where Rise is the change in y and Run is the change in x.
From the two given points, starting at (0,-15) and ending at (10,0):
Rise = (0-(-15)) = +15
Run = (10-0) = 10
Rise/Run (slope) = 15/10 or 1.5
The equation becomes y = (1.5)x + b
We know b, since it is the value of y when x=0. The point (0,-15) says -15 when x=0. You can also can find b by entering either of the two given points and solving for b. I'll pick (10,0):
y = (1.5)x + b
(0) = (1.5)*(10) + b
0 = 15 + b
b = -15
The equation is y = (1.5)x - 15
