Question

simplify
1. x^2-5x+4/x-1
2. 9x^2-3x/3x i got 3x-1 for this
3. x-y/x+y+x+y/x-y i got 2*x is this correct

Answer 1

your question doesnt make sence??? lol

Answer 2

1. \[\frac{x^2-5x+4}{x-1}=\frac{(x-4)(x-1)}{x-1}=x-4\]

Answer 3

lol i wrote it how it was the second two i attempted myself

Answer 4

like how Mertsj did

Answer 5

2. Correct
3.
\[\frac{x-y}{x+y}+\frac{x+y}{x-y}=\frac{(x-y)^2+(x+y)^2}{(x-y)(x+y)}=\]
\[\frac{x^2-2xy+y^2+x^2+2xy+y^2}{(x-y)(x+y)}=\frac{2x^2+2y^2}{x^2-y^2}\]
