Answer:

B. -7[tex]x^{2}[/tex] + 3x + 5

Step-by-step explanation:

(-3[tex]x^{2}[/tex] + x + 5) - (4[tex]x^{2}[/tex] - 2x)

-3[tex]x^{2}[/tex] + x + 5 - 4[tex]x^{2}[/tex] - 2x

Combine like terms

-3[tex]x^{2}[/tex] - 4[tex]x^{2}[/tex] = -7[tex]x^{2}[/tex]

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

5

-7[tex]x^{2}[/tex] + 3x + 5

I hope this helps :))
