could someone help me with math?

Question

Multiply the following binomials.

(4y−3/2)(y+1/2)

Answer 1

I would use the FOIL method to multiply these out!

(4y−3/2)(y+1/2)

=4y^2 - 3/2y + 2y - 3/4

=4y^2 + 1/2y - 3/4

Answer 2

Michael, we have to multiply eveything in the first set of parentheses by everything in the 2nd.

 

4y(y) = 4y²

4y(1/2) = 2y

-3/2(y) = -3/2y

-3/2(1/2)=-3/4

 

Combining like terms, we get 4y² + 1/2y - 3/4

 

Hope this helps!
