$\large{\rm{\implies{\frac{9 {a}^{2} - 30ab + 25 {b}^{2}}{3a - 5b}}}}$

$\large{\rm{\implies{\frac{a(9a - 30b + 25 {b}^{2})}{3a - 5b}}}}$

$\large{\rm{\implies{\frac{(a + b)(9a - 30 + 25 b)}{3a - 5b}}}}$

$\large{\rm{\implies{\frac{( \cancel{a} + \cancel{b} )(9a - 30 + 25 b)}{3 \cancel{a} - 5 \cancel{b}}}}}$

$\large{\rm{\implies{\frac{( \cancel{a} + \cancel{b} )(9a - 30 + 25 b)}{3 - 5 }}}}$

$\large{\rm{\implies{\frac{ \cancel{9}a \cancel{ - 30} + 25 b}{ \cancel{3} \cancel{ - 5 }}}}}$

$\large{\rm{\implies{3a - 6 + 25b}}}$
