3 x^{3} -12x

The greatest common factor we can pull out is 3x, leaving us with this:

3x( x^{2} -4)

We can factor further, giving us the answer of:

3x( x+2)(x-2)

You factor by the GCF (Greatest Common Factor). So, the equation would look like this:

3x ( x^2 - 4)

And, that's your answer.

6x+32=−2x
velikii [3]
Whatever you do to one side, you have to do to the other.
Try to get all the x values and regular values together.
To do that, just subtract both sides by 6x to cancel it out on one side and subtract it from the other side:

6x-6x+32=-2x-6x
=
32=-8x
now divide both sides by -8 to get the x by itself

32/-8=-8/-8x
= 32/-8=x
-4=x
so your answer is: x= -4
