multiply numerator and denominator by 3x

result:

( x^2 - 12x)/(15x + 3)

Ok ive attempted what i think might be an answer...

x-12

----

3

----

5x+1

----

x

Right?

and then i flip flopped it so i could multiply it..

(x-12) x

------ x -----

3 5x+1

(the x in the middle symbolizes multiplication)

so after i multiply them out i get...

(x^2)-12x

---------

15x +3

so is that the right answer?
