Question

Simplify each expression.
9. (4a – b) + (3a – 5b)
10. (x2 + 7x – 4) + (x2 + 9)
11. (g + 6)(g + 4)
12. 3m(-6m – 2m2p – 10p)

Answer 1

This is easy....you just have to operate on the like terms.

Answer 2

In the third one:

\( \color{Black}{\Rightarrow (g + 6)(g + 4) = g(g + 4) + 6(g + 4) }\)

Answer 3

9. 4a - b + 3a - 5b

10. x^2 + 7x - 4 + x^2 + 9

11. (g x g) + (g x 4) + (g x 6) + (6 x 4)

12. (3m x -6m) + (3m x -2m^2 p^2) + (3m x -10p)
