Question

factorise
$x {6} - y {6}^{?}$
​

Answer 1

⭐Solution⭐

✏Factorise of (x^6 - y^6)

✒we know,

(a²-b²)= (a+b)(a-b)

so,

(x^6 - y^6)

= (x³)² - (y³)²

= (x³+y³)(x³-y³)

= (x+y)(x²+y²-xy)(x-y)(x²+y²+xy)

⏩Inportant Formula

♠ (a³-b³)= (a-b)(a²+b²+ab)

♠ (a³+b³)=(a+b)(a²+b²-ab)

♠ (a²-b²)=(a+b)(a-b)
