algebra help:3over2-radx?

Question

the directions say to rationalize the denominator please give m the steps i have the answer

Answer 1

3/(2-sqrt(x))
= 3(2+sqrt(x)/ [(2-sqrt(x))*(2+sqrt(x)]
= [6+3sqrt(x)](4-x)

You need to multiply the denominator and numerator by
2+sqrt(x). This rationalizes the denominator because
(2-sqrt(x))*(2 +sqrt(x)0 = 2^2 - (sqrt(x))^2 = 4 - x.
