Question

How do you evaluate `(\frac { y } { 4} + 3) ( \frac { y } { 3} - \frac { 3} { 4} )`?

Answer 1

`y^2/1+13/16y-9/4`

Explanation:

Since it is:

`(a+b)(c+d)=ac+ad+bc+bd`

you would multiply term by term the polynomials:

`y^2/12-3/16y+y-9/4`

and then sum the like terms:

`y^2/12+13/16y-9/4`
