Question

Product of (x+2)(x-2)(x2+4)​

Answer 1

$\star\:\:\bf\large\underline\blue{Question:-}$

• Find the product of $(x + 2)(x - 2)( {x}^{2} + 4)$

$\star\:\:\bf\large\underline\blue{Solution:-}$

Before we start, we have to know the identity to solve the problem. Only 1 identity is enough for solving this problem i.e.,

• $(x + y)(x - y) = {x}^{2} - {y}^{2}$

Now, we will solve the problem.

$(x + 2)(x - 2)( {x}^{2} + 4)$

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

$= {x}^{4} - 16$

$\star\:\:\bf\large\underline\blue{Answer:-}$

• Answer is ${x}^{4} - 16$
