Question

How do you simplify `-3y ( 4y + 6) ^ { 2}`?

Answer 1

`-48y^3-144y^2-108y`

Remember GEMS or PEMDAS! (parenthesizes, exponents, division/multiplication, addition/subtraction)

Explanation:

Start with the exponent, you're going to have to use the FOIL rule.

`-3y[4y(4y+6)+6(4y+6)]`

`-3y(16y^2+48y+36)`

Now, distribute the `-3y.`

`-48y^3-144y^2-108y`
