$9a ^{ 2 } -25b ^{ 2 }$
$\left ( 3 a - 5 b \right ) \left ( 3 a + 5 b \right )$
Arrange the expression in the form of factorization..
$\color{#FF6800}{ 9 } \color{#FF6800}{ a } ^ { \color{#FF6800}{ 2 } } \color{#FF6800}{ - } \color{#FF6800}{ 25 } \color{#FF6800}{ b } ^ { \color{#FF6800}{ 2 } }$
$ $ Factorize to use the polynomial formula of sum and difference $ $
