x= -5 or 5
Work Step by Step
Factor the binomial using the formula for factoring a difference of squares. x$^2$-25=0 (x+5)(x-5)=0 Set each variable factor as equal to zero and then isolate the variable to find the solutions. x+5=0 or x-5=0 x=-5 or x=5 Enter the equation into your graphing utility to observe that the graph crosses the x-axis at -5 and 5.
