Question

Use the box method to distribute and simplify (-5x-2)(-2x^2+6x).

Answer 1

`10x^(3) - 26x^(2) - 12x`

Explanation:

1) Use the FOIL method: (a+b)(c+d)=ac+ad+bc+bd.

`10x^(3) - 30x^(2) + 4x^(2) -12x`

2) Collect like terms.

`10x^(3) + (-30x^(2) +4x^(2) )-12x`

3) Simplify.

`10x^(3) - 26x^(2) -12x`

Therefor, the answer is, 10x^3 - 26x^2 - 12x.
