Question

Simplify Completely:

x^2+x-12/x^2-x-20 divided by
3x^2-24x+45/12x^2-48x-60

Answer 1

factorise numerator and denominator . you will get the final answer
(x+1)/(x-5)

Answer 2

Thank you! Do you mind showing me the work? I actually want to learn aswell, and not just get the answer. But thank you so much!

Answer 3

(a/b)divided by(c/d) = (a*d)/(b*c)
use this and factorise all the equations and you will get this
((x-3) (x+4) * (x-5) (x+1)) / ((x-5) (x+4) * (x-5) (x-3))

I solved it in here...check it if u want

Answer 6

\[\LARGE \cfrac{\cfrac{x^2+x-12}{x^2-x-20}}{\cfrac{3x^2-24x+45}{2x^2-48x-60}}=\cfrac{\cfrac{(x-3)(x+4)}{(x-5)(x+4)}}{\cfrac{3(x-5)(x-3)}{2(x^2-24x-30)}}\]


obviously I can't finish it... Latex is killing me !! :(

Answer 9

@Kreshnik oops......se mos me pyete dhe s'ta thashe :P xD

Answer 10

Kreshnik si i faktorizove ato aq shpejt :O:O

Answer 11

a is the answer
