Question

use suitable identies to find the following products :(3-2x)(3+2x)​

Answer 1

=>(3+2x)(3-2x)

Using the formula (a+b)(a-b)=a^2-b^2 we get,

=>(3)^2-(2x)^2

=>9-4x^2

Answer 2

Question:-

$(3 - 2x)(3 + 2x)$

$\:$

Answer:-

Using the Identity :-

$(a +b )( a- b) = {a}^{2} - {b}^{2}$

$(3 - 2x)(3 + 2x)$

$(3) {}^{2} - ({2x})^{2} = 9 - {4x}^{2}$
