Answer 1

Steps:

So firstly, let's set up our equation. Since we are finding the difference between the 2 polynomials, this is going to be a subtraction problem:

$-0.06x^2+32x-100-(-0.04x^2+26x-170)$

Next, foil -(-0.04x² + 26x - 170). (Treat the minus sign on the outside as -1):

$-0.06x^2+32x-100+0.04x^2-26x+170$

Next, combine like terms:

$(-0.06x^2+0.04x^2)+(32x+(-26x))+(-100+170)\\-0.02x^2+6x+70$

Answer:

In short, your final answer is C: -0.02x^2 + 6x + 70
