simply cross multiply.
(x+5) (x+4) ------ * ------ (x-2) (x-2)
so just multiply x+5 times x-2? and the other way around?
now just multiply.. (x+5)(x+4) ---------- (x-2)(x-2)
still don't get it lol

Lol, i simply cross multiplied. write this down in our book, then u will understand.
solve this (x+5)(x+4)=(x-2)(x-2)

x^2 +9x +20 =x^2 +2x -8

x=-28/7 = -4 x=-4
ok I see where you got the 20 and the 8 but where did the 9 come from?
after multiplying them. FOIL.
but x not can being -4 because than the fraction (x-2)/x-4) is undefined
sorry the fraction x-2/x+4
