Question

(a²x²-2ax+2) ( a²x²+2ax+2)
Find the product with the help of formula. show the process. the correct answer will be marked as brainliest.​

Answer 1

Here,

$\: \: \: \: \: a = a²x²$

$\: \: \: \: \: b = 2ax$

$\: \: \: \: \: c = 2$

Using the formula,

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

$= {( {a}^{2} {x}^{2} ) }^{2} - {(2ax)}^{2} + {2}^{2} + 2( {a}^{2} {x}^{2} )(2)$

$= {a}^{4} {x}^{4} - 4 {a}^{2} {x}^{2} + 4 + 4 {a}^{2} {x}^{2}$

$= {a}^{4} {x}^{4} + 4$
