D: which of the following is a solution of x2 + 6x = –22? –3 ± isquare root of 13. –3 ± isquare root of 52. –6 ± isquare root of 13. –6 ± isquare root of 52.

-3 +/- square root of 13

I  dont  know much about vertexes but i know to solve this function you need to use foil method and then corresponmd the vertex with the actual coordinates, hope i !
