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

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

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 $-3y.$

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

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