Question

((5x+5)/(x^2-3x-4))/((1)/(x^2-9x+20))
how do you simplify this?????

anonymous · Answer

The first step i would take is factoring all of the equations and then maybe taking the first set multiplied times the reciprocal of the second set would be my guess looking at it just to start at least

anonymous · Answer

ok so i multiplied by the reciprocal and got (x^2-45x+100)/(x^2-3x-4)

anonymous · Answer

$$\frac{ 5(x+1 }{ (x-4)(x+1) }* \frac{ (x-5)(x-4) }{ 1 }$$ is what i was referring to ^^

see what i did?

anonymous · Answer

yeah I think so

anonymous · Answer

ok all I did was take each section and make it as simple as possible then knowing that it was a simplification problem I knew when i finished lots of terms are going to cancel you see the ones that are going to cancel out now right?

anonymous · Answer

so it would come out to 5x-25?

anonymous · Answer

yep

anonymous · Answer

alright so one question, I'm just being stupid but how did you factor it all out?

anonymous · Answer

alright nevermind i figured it out! thanks for the help!!

anonymous · Answer

lol no problem
