Question 565350: I need to use the distributive property to show this:
-3x(x-3) This is what I got...

-3x*x - -3x*3
Am I doing this right? The two negative signs don't look right.?.

Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
the problem is:
-3x * (x-3)
you distribute as follows:
(-3x * x) + (-3x * -3)
you then simplify this to:
(-3x^2) + (9x) which becomes:
-3x^2 + 9x
your answer is:
-3x*x - -3x*3
this simplifies to:
-3x^2 + 9x
looks good to me.
