## Introductory Algebra for College Students (7th Edition)

Rewrite the equation in standard form. x$^2$=14x-49 x$^2$-14x=-49 x$^2$-14x+49=0 Factor the trinomial. (x-7)(x-7)=0 (x-7)$^2$=0 Set each variable factor as equal to zero and then isolate the variable to find the solutions. x-7=0 x=7 Enter the original equation into your graphing utility to observe that the graph crosses the x-axis at 7.
