x=-3 or -2
Work Step by Step
Factor the trinomial. x$^2$+5x+6=0 (x+3)(x+2)=0 Set each variable factor as equal to zero and then isolate the variable to find the solutions. x+3=0 or x+2=0 x=-3 or x=-2 Enter the original equation into your graphing utility to observe that the graph crosses the x-axis at -3 and -2.
