Question

factorise : (a^4-8a^2b^2+16b^4)-9z^2


please solve it I will mark you as brainliest......​

Answer 1

Answer:

(a^2+b^2+16)×(a^2+b^2-16)

Step-by-step explanation:

If u observe closely u will see that the question can be solved by (a+b)^2 identity then using the identity factorise the expression in the bracket.

then when u get the answer then u will see that u can solve the sum by a^2-b^2 identity. then when u solve the identity u will get the above answer
