Question

how to factorise a⁴-b⁴​

Answer 1

Step-by-step explanation:

The answer is given in the pic..

Answer 2

The factorization of a⁴-b⁴​ is (a²+b²)(a+b)(a-b)

Step-by-step explanation:

The given expression is

a⁴-b⁴​

Write this expression in perfect square form

(a²)²-(b²)²

Use the formula for difference of squares: x²-y²=(x+y)(x-y)

(a²+b²)(a²-b²)

Again apply the formula for difference of squares

(a²+b²)(a+b)(a-b)

Thus, the factorization of a⁴-b⁴​ is (a²+b²)(a+b)(a-b)
