Question

How do you multiply `2y(y-4)`?

Answer 1

`2y^2 - 8y`

Explanation:

Use distribution `a(b + c) = ab + ac` and the exponent rules`x = x^1 " and " x^m * x^n = x^(m + n)`:

Given: `2y (y - 4)`

Distribute: `2y (y - 4) = 2y y + 2y(-4)`

Simplify using multiplication and the exponent rules:

`= 2y^2 -8y`
