LAST AND FINAL ATTEMT WILL GIVE BRANLIEST PLS COME LOOK! WILL BE GREATFUL COME LOOK I NEED ALL THE HELP I CAN GET!!! Which explains how to show that X= -8/3 is a root of 9x^2+48x+64=0?

A) Substitute X= -8/3 back into 9x^2+48x+64=0 and simplify to show the values of A and C remain perfect squares.
B) Substitute X= -8/3 back into 9x^2+48x+64=0 and simplify to show that a true statement results.
C) Graph 9x^2+48x+64=0 to show that X= -8/3 is where the parabola crosses the y -axis.
D) Graph 9x^2+48x+64=0 to show that the parabola's vertex is just above the value X= -8/3 .
