3/x+4 +x-5/x+1
x+4 and x+1 are the lcds
3x+3+x-5(x+4)
3x+3+x^2-x-20
x^2+2x-17/x+1 x+4

I think this is a simplification qn rite?
(3/x+4)+ (x-5 / x+1)
= [3(x+1) + (x-5)(x+4)] / [(x+4)(x+1)]
= [3x+3 + x^2 - x -20] / [(x+4)(x+1)]
= (x^2 + 2x -17) / [(x+4)(x+1)]

Dont think its posible without you knowing what the equation is equal to
