Explanation:
#"the equation of a parabola in "color(blue)"vertex form"# is.
#•color(white)(x)y=a(x-h)^2+k#
#"where "(h,k)" are the coordinates of the vertex and a"#
#"is a multiplier"#
#"To obtain this form "color(blue)"complete the square"#
#y=x^2+2(13/2)x+169/4-169/4+120/4#
#color(white)(y)=(x+13/2)^2-49/4larrcolor(red)"in vertex form"#
