This is MJMATH, good morning to you. How would I use rationalization to simplify the expression; 9t2 --------------------- t + 2 - 2 √ t + 1 Note: above the line = 9 t squared below the line = t + 2 - 2 ( the square root of t + 1). Thank you

What exactly are you looking to do? You can rationalize the function by multiplying the top and bottom by the radical of the bottom ( (t+2)+2[(t+1)^(1/2)] ), but to be quite frankly honest, it doesn't really give you a better looking or more simple answer. By rationalizing the function, I mean moving the radical from the bottom to the top.

OpenStudy (shadowfiend):

Hm. I think it's better looking. Doesn't the denominator disappear altogether?

OpenStudy (anonymous):

Oh wait, you're right, I didn't distribute the 4 properly

OpenStudy (anonymous):

and I meant to say the conjugate of the bottom, not the radical
