  -5x² -4x +8

Step-by-step explanation:

Eliminate parentheses and collect terms.

  (-2x² +3) -(3x² +4x -5)

  = -2x² +3 -3x² -4x +5

  = (-2-3)x² -4x +(3 +5)

  = -5x² -4x +8

-5x² -4x +8  

remove parentheses and collect terms.

 (-2x² +3) -(3x² +4x -5)

 = -2x² +3 -3x² -4x +5

 = (-2-3)x² -4x +(3 +5)

 = -5x² -4x +8
