$\huge\bold{\gray{\sf{Answer:}}}$

Explanation:

$(4x - 7)(4x - 7)$

Here ,same term is occur two times which is in product form so we can also write as (4x-7)^2

Here , identity is used:-

$\bold{\boxed{ {(x - y)}^{2} = {x}^{2} + {y}^{2} - 2xy}}$

$= > {(4x - 7)}^{2} = {(4x)}^{2} + {(7)}^{2} - 2(4x)(7)$

$= > 16 {x}^{2} + 49 - 56x$

$= > 16 {x}^{2} - 56x + 49$
