Question

What is the simplified form of this expression?

Answer 1

Answer:

B. -7$x^{2}$ + 3x + 5

Step-by-step explanation:

(-3$x^{2}$ + x + 5) - (4$x^{2}$ - 2x)

-3$x^{2}$ + x + 5 - 4$x^{2}$ - 2x

Combine like terms

-3$x^{2}$ - 4$x^{2}$ = -7$x^{2}$

x - -2x = x + 2x = 3x

5

-7$x^{2}$ + 3x + 5

I hope this helps :))
