Question

Assume you've arrived at the following solution:

(5x^2 + 7x − 12) − (x^2 − 2x − 35)

What will be the final step? Perform the step, and show your work.

Answer 1

see below

Explanation:

Nothing inside the parentheses can be combined. So, subtract the quadratic expression by distributing the negative sign:

(5x2 + 7x − 12) − (x2 − 2x − 35)

= 5x2 + 7x − 12 − x2 + 2x + 35

= 5x2 − x2 + 7x + 2x − 12 + 35

= 4x2 + 9x + 23

Answer 2

Simplify is your next step. Answer is: 4x^2+9x+23
