You can put this solution on YOUR website!
x(x-2)=0
Then
x = 0 0r
x-2 = 0, x = 2
Two possible solutions:
x = 0,2

+x%2A%28+x-2+%29+=+0+
There are 2 things you can do to the
left side to make it zero.
You can make +x+=+0+. Then you have:
+0%2A%28+0+-+2+%29+=+0+
+0%2A%28-2%29+=+0+
+0+=+0+
-----------
The other thing you can do is:
Make +x+=+2+. Then you have:
+2%2A%28+2+-+2+%29+=+0+
+2%2A0+=+0+
+0+=+0+
------------
So,
+x+=+0+
+x+=+2+
are the solutions
----------------
+x%2A%28+x-2+%29+=+0+
+x%5E2+-+2x+=+0+
This is for finding roots
Here is the equation:
+y+=+x%5E2+-+2x+
+graph%28+400%2C+400%2C+-6%2C+6%2C+-2%2C+6%2C+x%5E2+-+2x+%29+
You can see the roots at ( 0,0 ) and ( 2,0 )
