How do you rationalize the numerator
Webif we just look at " sqrt (x+5) -2 " as the denominator without rationalizing, we know it cannot equal zero. So we solve for zero: "sqrt (x+5) -2 = 0" --> x = -1 alright, what if we test this? … WebTo do these problems, you will need to rewrite the expression by rationalizing the numerator, which means rewriting so that there are no square roots in the numerator. To rationalize the numerator, you multiply the both numerator and the denominator by the conju- gate of the numerator.
