Question 85146: factor
18x^3-36x^2
Answer by bucky(2189)   (Show Source):
You can put this solution on YOUR website! Given:
.
18x^3-36x^2
.
To factor this, first note that each term contains 18x^2 as a factor. You can therefore
factor out 18x^2 and the problem is then simplified to:
.
18x^2(x - 2)
.
This can be checked by multiplying it back together to convince yourself that it does
take you back to the given problem.
.
If you wish to factor it further, notice that 18 factors into 2*3*3 and x^2 factors
into x*x so that the 18x^2(x-2) can be further factored to give:
.
2*3*3*x*x*(x-2)
.
Hope this helps you to see your way through the problem.
