WHOLE ANSWER EXPLAINED STEP-BY-STEP

m^{4}-256m4−256

= (m^{2})^{2}-16^{2}=(m2)2−162     [∵ m^{4} = (m^{2})^{2}m4=(m2)2 and 16^{2} = 256162=256

= (m^{2}+16)(m^{2}-16)=(m2+16)(m2−16)

= (m^{2}+16)(m^{2}-4^{2})=(m2+16)(m2−42)

= (m^{2}+16)(m-4)(m+4)=(m2+16)(m−4)(m+4)

For the factorisation, I have used this identity: a^{2}-b^{2} = (a+b)(a-b)a2−b2=(a+b)(a−b)

Hope this may help you. 

If you have any doubt, then you can ask me in the comments.
