Work Step by Step
Rewrite the equation in standard form. x$^2$=12x-36 x$^2$-12x=-36 x$^2$-12x+36=0 Factor the trinomial. (x-6)(x-6)=0 (x-6)$^2$=0 Set each variable factor as equal to zero and then isolate the variable to find the solutions. x-6=0 x=6 Enter the original equation into your graphing utility to observe that the graph crosses the x-axis at 6.
