Question

rationalize the denominator x2 square root 2x + 5

Answer 1

\[\frac{ x ^{2} }{ \sqrt{2x+5} }\]
so we need to multiply the fraction by 1 but one is square root 2x+5
therefore
\[\frac{ x ^{2} }{ \sqrt{2x+5}} \times \frac{ \sqrt{2x+5} }{\sqrt{2x+5} }\]

Answer 2

will you simplify that for me?
