Question

Find what he did wrong and fix it. Need answer fast with all the steps included please. NEED HELP

Answer 1

Simplify The numerator

$4 {a}^{2} - {b}^{2} = (2a + b)(2a - b)$

$\sqrt{ \frac{(2a + b)(2a - b)}{9a} }$

$\sqrt{9a} = \sqrt{9} \times \sqrt{a}$

$3 \times \sqrt{a}$

$\sqrt{ \frac{(2a + b)(2a - b)}{3 \sqrt{a} } }$

RATIONALIZE

$\frac{ \sqrt{a} \sqrt{(2a + b)(2a - b)} }{3 \sqrt{a } \times \sqrt{a} }$

$\sqrt{ \frac{a(2a + b)(2a - b)}{3a} }$. This is the answer
