Help with summer math packet!?

Question

summer math packet.....

write as a product of two binomials: 5x(x+2) - 4(x+2)

if you could explain that would be great

thank you.

Answer 1

5x(x+2)-4(x+2)

multiply 5x and 4 into the parenthesis

5X^2 + 10x - 4x - 8

5x^2 + 6x - 8

the product is a trinomial

Answer 2

25x^2 + 10x - 4x + 8 = 25x^2 +6x - 8

1. Distribute the 5x to the x + 2. Do the same: 4 times x + 2.

2. Add like terms. For example: 10x - 4x = 6x.

3. Rewrite your answer.
