Answer
$8y^4+4y^3-2y^2-3y-3$
Work Step by Step
Multiply 4y^2 by each term in the second expression:
$4y^2(2y^2)+4y^2y+4y^2*1+(-3(2y^2)-3y-3*1)$
Then, simplify and combine like terms. $8y^4+4y^2y+4y^2*1+(-3(2y^2)-3y-3*1)$
Work step by step to combine like terms. Remember exponent rules.
$8y^4+4y^2y+4y^2-3(2y^2)-3y-3)$
Continue to simplify.
$8y^4+4y^3+4y^2-6y^2-3y-3$
Subtract 4-6 to get -2.
$8y^4+4y^3-2y^2-3y-3$
All done!
