$36a ^{ 2 } -1$
$\left ( 6 a - 1 \right ) \left ( 6 a + 1 \right )$
Arrange the expression in the form of factorization..
$\color{#FF6800}{ 36 } \color{#FF6800}{ a } ^ { \color{#FF6800}{ 2 } } \color{#FF6800}{ - } \color{#FF6800}{ 1 }$
$ $ Factorize to use the polynomial formula of sum and difference $ $
$\left ( \color{#FF6800}{ 6 } \color{#FF6800}{ a } \color{#FF6800}{ + } \color{#FF6800}{ 1 } \right ) \left ( \color{#FF6800}{ 6 } \color{#FF6800}{ a } \color{#FF6800}{ - } \color{#FF6800}{ 1 } \right )$
$\left ( \color{#FF6800}{ 6 } \color{#FF6800}{ a } \color{#FF6800}{ + } \color{#FF6800}{ 1 } \right ) \left ( \color{#FF6800}{ 6 } \color{#FF6800}{ a } \color{#FF6800}{ - } \color{#FF6800}{ 1 } \right )$
