Question

Can someone take a look at this? I was stumped. File attached. Medal for anyone who gets the answer.

Answer 1

did you try to cross-multiply ?

Answer 2

I don't even know where to start with this :/

Answer 3

\(\Large \dfrac{a}{b} - \dfrac{c}{d} = \dfrac{a\times d - b \times c}{b \times d}\)
this is basic math.
apply this to your question. its your fist step, can you try ?

Answer 4

\(\large \dfrac{5}{x^2+x-2} - \dfrac{3}{x^2-4x+4} = \dfrac{5(x^2+x-2)-3(x^2-4x+4)}{(x^2+x-2)(x^2-4x+4)}\)

can you try to simplify the numerator there ?
