Answer 1

$\bold{ ⇒\dfrac{4 - \sqrt{25 - a} }{a - 9}}$

$\bold{ = \dfrac{4 - \sqrt{25 - a} }{a - 9} \times \dfrac{4 + \sqrt{25 - a} }{4 + \sqrt{25 - a} } }$

$\bold{ = \dfrac{16 - (25 - a)}{(a - 9)(4 + \sqrt{25 - a} )} }$

$\bold{ = \dfrac{ - 9 + a}{(a - 9)(4 + \sqrt{25 - a} )} }$

$=$$\bold{\red{ \dfrac{ 1}{(4 + \sqrt{25 - a} )}}}$
