Thread: Factoring and rationalizing

1/ sqroot(x) - 1/2 / x-4


I first simplified by multiplying by 2sqroot(x) = 2-sqroot(x) / (x-4) (2sqroot(x)) than i was going to rationalize the numerator by multiplying by 2+ sqroot(x) but that seemed too complicated.

Where did i go wrong?

Why dont you type in latex or give proper brackets?? It helps a lot....
is your question:Rationalize and factorize

I dont know how to, but well i suppose its the same but its (1/rootx - 1/2 ) / (x-4)

Hello, skg94!

I first simplified by multiplying by .and got: .

Then I was going to rationalize the numerator by multiplying by
but that seemed too complicated. . But did you try it?

Where did i go wrong? . Nowhere . . . your work is correct!
