Question 118762
For quadratic equations, solve it by getting it in the form ax^2+bx+c=0.
So subtract 15x and add 10 to both sides to get 3x^2-17x+10=0.  Now either factor into two binomials or use the quadratic formula to solve for x.  I'll factor:
(3x-2)(x-5)=0
I got this by putting (3x-__)(x-__) and trying different factor pairs of 10 for the spaces (10 and 1 or 5 and 2).
So 3x-2=0 and x-5=0
x=2/3,5
