Question

Simplify each expression by distributing and combining like terms

1) 7(6x+5)
2) -2(x+5)
3) -2(x-5)

Answer 1

1: 42x + 35

2: -2x-10

3: -2x+10

Explanation:

To answer these questions, what we need to do is multiply out the brackets.

You can do this by multiplying the outside number by the terms on the inside.

For example if we do this with the first one:

7 x 6x = 42x

7 x 5 = 35

add them together = 42x + 35.

You use the same technique for 2) and 3).
