Introductory Algebra for College Students (7th Edition)

Rewrite the equation in standard form. x$^2$=4x x$^2$-4x=0 Factor out the GCF. x(x-4)=0 Set each variable factor as equal to zero and then isolate the variable to find the solutions. x=0 or x-4=0 x=0 or x=4 Enter the original equation into your graphing utility to observe that the graph crosses the x-axis at 0 and 4.
