Question

factorize: 2x^4-128x​

Answer 1

Answer:

2x(x-4)(x^2+16+8x)

Step-by-step explanation:

by using the formula (x^3-a^3)

Answer 2

Step-by-step explanation:

taking 2x as common2x(x^3-64)

now, we know that,64 is the cube root of 4

and x3 is the cube root of x1

using the formula a3-b3

a3-b3=(a-b) (a^2+ab+b^2)

2x (x-4) (x2+x.4+4^2)

2x (x-4) (x2+4x+16)
