The factories form is m^4-256=(m^2+16)(m+4)(m-4)

Step-by-step explanation:

Given : Expression m^4-256.

To find : Factories the expression ?

Solution :

To factories the expression we can re-write as,

m^4-256=(m^2)^2-(16)^2

Using algebraic identity, a^2-b^2=(a+b)(a-b)

m^4-256=(m^2+16)(m^2-16)

Again re-write as,

m^4-256=(m^2+16)(m^2-4^2)

Again apply same identity,

m^4-256=(m^2+16)(m+4)(m-4)

Therefore, the factories form is m^4-256=(m^2+16)(m+4)(m-4).
