Question

What is the completely factored form of p4 – 16?

Answer 1

Answer :-

No , it is not completely factored form of the expression.

The complete factored form will be as follows :-

$p^4 - 16$

It can be written as

$=> (p^2)^2 - (4 )^2$

It is on the formula of

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

Here , a = p² and b = 4

Again it can be written as

$=> (p^2 + 4) ( p^2 - 4)$

Hope it helps you :)

Thanks :)
