Question

Factorize the following expression please.

x to the power of 4-16

Answer 1

\[x^4 - 16\] that's difference of two squares

Answer 2

Hint: \[(a^2 - b^2) = (a+b)(a-b)\]

Answer 3

x^4-16=(x^2+4)(x^2-4)=(x^2+4)(x+2)(x-2)

Answer 4

\(\Large \color{MidnightBlue}{\Rightarrow x^4 - 4^2 }\)


\(\Large \color{MidnightBlue}{\Rightarrow (x^2)^2 - 4^2 }\)


Try to factorize this by this identity: a^2 - b^2 = (a + b)(a - b)
