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!
