Question

Express the product in simplest form.

Answer 1

`(8)/(2x+8) * ( x^(2)-16 )/(4)`

1. Cross cancel

`(4)/(2x+8)* ( x^(2) -16)/(1)`

2. Multiply numerators
4*x²-16 = 4x²-64

3. Multiply denominators
2x+8*1 = 2x+8


`(4 x^(2) -64)/(2x+8)`

4. Divide

`(4 x^(2) -64)/(2x+8) = 2x-8`

5. Simplify
2(x-4)

Answer is 2(x - 4)
