Answer:

B. 3x² – 10x + 13

Step-by-step explanation:

given:

f(x) = 3x² – 8x + 5

g(x) = 2x – 8

f(x) - g(x)

= (3x² – 8x + 5) - (2x – 8)

= 3x² – 8x + 5 - 2x + 8

= 3x² – 10x + 13

-4(-3x - 8) - 4x + 8 = -8x + 40
Andrew [12]
First we expand and combine the terms on the left side.  This gives us

12x + 32 -4x + 8 = -8x + 40 

8x + 40 = -8x + 40.  Because the two sides cancel each other out when you try and bring all the x to one side, the answer is x = 0.
