You need to remember that the is actually a 1 in front of the second expression.

(x28x+7)1(6x2+7x3)

The first set of parentheses can drop since there is merely a 1 in front of them. You will need to distribute the 1 to the second set of parentheses.

x28x+76x27x+3

Now you are ready to combine like terms. Remember that the sign in front of the term moves with the term.

x26x28x7x+7+3

Giving me the following answer:

5x215x+10
