Question

Which expression is equivalent to 64 − 9x2?

Answer 1

(8)2-(3x)2 is the correct formula

Answer 2

Answer:

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

Step-by-step explanation:

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 )
