Question

7. Factorize the following by using suitable identities:

(c) m⁴ + 2m²n² +n⁴​

Answer 1

Answer:

(m 2 +n 2) 2

Step-by-step explanation:

using the formula of (a+b) 2

Answer 2

Step-by-step explanation:

$m^{4} + 2m^{2}n^{2} + n^{4}$       (using the identity: $a^{2} +2ab+b^{2} = (a+b)^{2}$

= $(m^{2})^{2} + 2*m^{2} *n^{2} +( n^{2} )^{2}$

= $(m+n)^{2}$ (Ans)
