Question

Solve 2x(x+4)(4x-9)=0.

Answer 1

Put each bit equal to 0.

Answer 2

x = 0 , -4 , 9/4

Answer 3

x=0 or x=-4 or x=9/4

Answer 4

same as prev question:
As estudier says, put each "bit" equal to 0 separately :)

So, first bit:
(2x)=0
x=0

Second bit:
(x+4)=0
x=-4

third bit:
(4x-9)=0
4x=9
x=9/4
