well, Google distributive property
4a(a^2) = 4 a^3
4a(7a) = 28 a^2
4a(4) = 16 a
Now add :)
=======================
distributive property again
2y(3y-2) = 6 y^2 - 4 y
-3(3y-2) = -9y + 6
now add
6 y^2 - 13 y + 6

works every time

@ weekend, one of your answers is wrong.

Just giving somebody the answer does not help anybody, and will get you banned.

@ Ruby, we "solve" equations, you have no equations.
What you meant is to 'simplify'

Show some steps to show me what you did , so I can see where you went wrong.
