(Picture) MULTIPLYING POLYNOMIALS AND SIMPLIFYING EXPRESSIONS PLEASE HELP!!!!

Answer 1

Answer:

$8y^3+6y^2-29y+15$

Step-by-step explanation:

$(4y-3)(2y^2 +3y-5)$

multiply 4y inside the parenthesis

$(4y)(2y^2 +3y-5)=8y^3+12y^2-20y$

Now we multiply -3 inside the second parenthesis

$(-3)(2y^2 +3y-5)=-6y^2-9y+15$

$(4y-3)(2y^2 +3y-5)$

$8y^3+12y^2-20y-6y^2-9y+15$

Now we combine like terms

$8y^3+6y^2-29y+15$
