-3x� +7x = 0 Solve
formula is (-b + or - sqrt(b^2-4ac))/2a
=(-7 + or - sqrt(49-0))/-6
therefore
x=-7+7/-6=0 or x=-7-7/-6=-14/-6=7/3

As the left side is very easy to factor, we can solve it by factoring.

As x is the common factor of the two terms, we factor x out.
So either x = 0 or -3x+7 =0
Therefor the two solutions are:
x = 0
Another solution can be obtained by solving -3x + 7 =0
