What is the set of real solutions for |x| ^2 - |x| -2 = 0

Answers

Answer 1

The set of real solution for  |x| ^2 – |x| -2 = 0 is x=-2 or x=2.

What is the real solution?

There are two real solutions for x if the discriminant's value is positive, which means that the graph of the solution has two distinct x-intercepts. This is called as the real solution.

Computation:

|x| ^2 – |x| -2 = 0

This can also be written as (|x| +1)(|x| -2)

then,

(|x| +1)(|x| -2) = 0

|x| +1 = 0 or |x| -2 = 0 (Using Zero factor principle)

Now, no solution for |x| +1 = 0 as x∈R

For |x| +2 = 0,

x = 2 or x = -2

Therefore, the solution for   |x| ^2—|x| -2 = 0 is x=-2 or x=2.

How do you write a binomial expression?

A binomial is a polynomial with the handiest terms. For example, x + 2 is a binomial, in which x and a pair of are separate terms. Also, the coefficient of x is 1, the exponent of x is 1 and a pair of is the regular here. Therefore, A binomial is a -time period algebraic expression that carries variable, coefficient, exponents and regular.
