4x^2=9x
4x^2-9x=0
x(4x-9)=0
x=0 and/or 4x-9=0
x=o or/an 4x=9
x=0 and/ or x=9/4
^these are the factors

you would have to bring the 9x to the other side to make the equation equal zero.
so then you would have 4x^2-9x=0
plug that into the quadratic formula, or just simply plug it into y= in a graphing calculator and see where it crosses the x-axix.
