Answer:

9 - 7x - x²

Step-by-step explanation:

-4x+2x2-x²+5-3x = -4x-3x+2x2+5-x²

I arranged the like terms together so it is easier to do the calculations.

-4x-3x+2x2+5-x² = -7x+4+5-x²

Simplify.

-7x+4+5-x² = 9-7x-x²

Answer:

[tex]x^{2} -7x+5[/tex]

Step-by-step explanation:

First, organize it by highest degrees: [tex]2x^{2} -x^{2} -4x-3x+5[/tex]

Then combine like terms: [tex]x^{2} -7x+5[/tex]
