Ok, you are going to multiply your binomials using the foil methode then simplify your answer

give me a sec to figure out the equation maker

no im not supposed to multiply it, it's (6a - 4) divided by (7a - 5)...

Alright either i am drawling a blank here or it's already in simplist terms due to the fact that there is no common factor. If you have the answer in the back of the book i will attempt to go step by step backwards to figure out what they want.

you can clear the fraction using an lcm and end up with -15a-9

with nothing under it?

It will clear the bottom if you do that. it would look something like ((7a-5)(6a-4)/(7a-5))-3(7a-5) the denomator will cancell and then you simplify

ok

its -15a + 11
anonymous
  • anonymous
yea i did it in my head but just for aperance sake i would rewrite that to 11-15a just because it looks better and makes it easier when you are doing harder operations later in your math career
