Answer:

x^2-9x+8

Step-by-step explanation:

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

Open the bracket first

2x^2-5x+3+x^2-4x+5

Collect like terms

2x^2+x^2-5x-4x+3+5

x^2-9x+8

So the final answer is x^2-9x+8

Complete the multiplication equation. (4) ( ) =-12<br>​
FrozenT [24]

Answer:

-3

Step-by-step explanation:

If we substitute the blank in for x, it will make the problem easier.

  • (4)(x)=-12

Divide each side by 4 to isolate x

  • x=-12/4

Solve, negative 12 divided by four is 3. So:

  • x=-3
