Question

x^4 – (x – y)^4
factorise the above

Answer 1

Answer:

hey cutie ✨

Step-by-step explanation:

here is your answer!

Answer 2

Answer:

x⁴-(x-y) ⁴

(x²)² - [(x-y)²]²

now, by the identity

a²-b² = (a+b) (a-b)

so, we have

[x²+(x-y)²][x²-(x-y)²]

now, by identity

(a-b)² = a²+b²-2ab

so, we have

[x²+(x²+y²-2xy)][x²-(x²+y²-2xy)]

[x²+x²+y²-2xy][x²-x²-y²+2xy]

[2x²-2xy+y²][2xy-y²]

[2x²-2xy+y²][2x-y][y]

y(2x-y) (2x²-2xy+y²)

hope it helps u
