1.) x = a

2.) x = b

3.) x = 0

4.) x = -b/a

5.) x = b/a

6.) x = ab

\(\rm ax^2=bx\)

apply subtraction,

\(\rm ax^2-bx=0\)

factor out an x,

\(\rm x(ax-b)=0\)

apply your Zero-Factor Property,

\(\rm x=0\qquad\qquad\qquad ax-b=0\)

And then solve for x in each case.
Clearly the first factor gives us x=0.

In the other factor tho,
add b,
then divide by a,

\(\rm x=\dfrac b a\)
