Question

1Q) Factorise (x4-1) using standard algebraic identities?

Answer 1

Answer:

(x²+1)(x+1)(x-1)

Step-by-step explanation:

x⁴-1 can be written as...

(x²)²-1

(x²)² - (1)² { (1)²=1

(x²+1)(x²-1) { a²-b² = (a+b)(a-b)

(x²+1)(x²-1²) { now x²-1 can also follow a²-b² property

(x²+1)(x+1)(x-1) {a²-b² = (a+b)(a-b)
