Question

Solve: x3 – 2x2 – 48x = 0

Answer 1

Factor out an X. x^2-2x-48.

Answer 2

x(x2 - 2x - 48) = 0
x(x-8)(x+6)=0
x = 0,8, -6

Answer 3

Teamwork.

Answer 4

x(x2 -2x-48) =o
consider
x(x2 -8x +6x - 48)=0
x=0
but (x2 -8x) +(6x-48)=0
x(x -8) + 6(x-8)=0
(x+6) (x-8)=0
x+6=0.................i
x-8=0.................ii
x=-6 and x=8
therfore x=0,-6 and 8
