Question

What is the coefficient of the term x^2 when the expression below is simplified? (5x^2-x-1)-(-3x^2-2x-5)

Answer 1

Answer: 8

Step-by-step explanation:

     Given:

(5x^2-x-1)-(-3x^2-2x-5)

     Rewrite:

(5x² -x -1) - (-3x² -2x -5)

     Distribute the negative:

5x² -x -1 + 3x² +2x +5

     Reorder terms:

5x² + 3x² -x +2x -1 +5

     Combine like terms:

8x² + x + 4

   The coefficient of the x² term is 8,

8x² + x + 4
