Answer 2

Answer:

Here is the answer =>

Step-by-step explanation:

3x^2-12x

3x(x-4)

3x(x-4)=0

So from here, x=0 and x=4.

Verification:-

1. 3x^2-12x=0

3(0)^2-12(0)=0 (Putting x=0).

0-0=0 (Hence verified).

2. 3x^2-12x=0

3(4)^2-12(4)=0 (Putting x=4).

3(16)-12(4)=0

48-48=0

0=0 (Hence verified).

So x=0 and x=4 is the required answer.
