Given : Expression =
64-9x^2

To find: An Equivalent expression to given expression

We find equivalent Expression by simplifying the given expression

Consider,

64-9x^2

$\implies 8^2 - (3x)^2$

by using an identity,
a^2-b^2=(a-b)(a+b) . we get,

$\implies (8-3x)(8+3x)$

Therefore, The equivalent Expression is ( 8 - 3x )( 8 + 3x )
