Question

factorize this = x^4-y^4

Answer 1

Answer:

=(x2+y2)(x+y)((x−y). Explanation: Since formula a2−b2=(a+b)(a−b) can be applied here. x4−y4 =(x2)2−(y2)2 =(x2+y2)(x2−y2)

=(x2+y2)(x+y)((x−y) Explanation: Since formula a2−b2=(a+b)(a−b) can be applied here. x4−y4 =(x2)2−(y2)2 =(x2+y2)(x2−y2) =(x2+y2)(x+y)((x−y)

Answer 2

Step-by-step explanation:

a^2-b^2= (a+b)(a-b)

x^4-y^4

=(x^2)^2-(y^2)^2

=(x^2+y^2) (x^2-y^2)

=(x^2+y^2) (x+y) (x-y)
