Fill in the blanks below with the correct coefficient for each term.

Question

Simplify: (x2+5x+8)−(3x2+2x−6)

f(x)−g(x)=___

Answer 1

Hello, Melanie,

I'm not clear on the second part of your question dealing with f(x) - g(x). There are no definitions for either function.

The first question asks us to simplify the expression. I'll assume x2 and 3x2 mean x² and 3x². Use x^2 to denote exponents.

Do the work in the parentheses first. This is straightforward for the first set:

x² +5x + 8

The second group is also easy, but note the "-" sign in front of it. We'll need to multiply each term by a -1:

−3x² - 2x + 6

Then group the like terms and add:

x² - 3x² +5x -2x + 8 + 6

-2x² +3x +14

I hope this helps,

Bob
