Hi my lil bunny!

Let's simplify step-by-step.


( x - 4x^2 + 7 ) - ( -5x^2 + 5x - 3)

Distribute the Negative Sign:


= x - 4^2 + 7 + -1 ( -5x^2 + 5x -3) \\= x + -4x^2 + 7 + -1 ( -5x^2) + -1 (5x) + ( -1) (-3)\\= x + -4x^2 + 7+ 5x^2 + -5x + 3

Combine Like Terms:


= x + -4x^2 + 7 + 5x^2 + -5x + 3 \\= (-4x^2 + 5x^2) + ( x + -5x) + ( 7 + 3) \\= x^2 + -4x + 10

Answer :
\boxed {x^2 -4x + 10}
