let x^3=t
so eqn will become
t^2-7t-8
I.e. (t-8)(t+1)
x=2 or -1
so eqn will become
t^2-7t-8
I.e. (t-8)(t+1)
x=2 or -1
Rishabh7755:
srry but this cant be applied on that... its a polynomial equation with different power
ohh..i got yr point
(x-2)(x+1)(x^2-x+1)(x^2+2x+4)
yrs how did u get this
yes*
hope it helped
(t-8)(t+1) subatitute t with x
Ohh thanku
u will see that form x^3-2^3 and x^3+1^3
Ya it really did
