First, get it into standard form by subtracting 8x from both sides:
x^2 - 8x = 0
Now you can see the common factor is 'x':
x(x - 8) = 0
That gives us two values of 'x' that are true:
x=0 and x=8.
Check.
0(0-8)=0. True
8(8-8)=0. True

Hello,
I'm assuming both x's are the same. If that's the case then here's how we do it:
X^2=8x Divide both sides by x which gives us:
x=8 You can see zero also fits the solution.
There we go. Check it out.
