Question

Factorize- x^(3)-12x(x-4)-64

Answer 1

try different no. substitute the value of x to get the the polynomial value Into 0.
if you got 4 as a factor then,divide the polynomial by x-4 ,u will get a second degree polynomial......find the the value of x through the quadratic equation or completiting square methord....

Answer 2

Hello friend


______________________________________________________________

x^(3)-12x(x-4)-64
x^(3)-64-12x(x-4)
this is the form of (a-b)³ = a³-b³-3ab(a-b)

x³-4³-3(4)(x)(4-x)

∴ (x-4)³
