5x² -36 + 36 = 0 Which value of x is the solution to this equation?

Please and thank you

What is the equation of the following graph in vertex form? parabolic function going down from the left through the point zero comma twelve and through the point two comma zero and turning at the point four comma negative four and going up through the point six comma zero and continuing towards infinity courtesy of texas instruments a: y = (x − 4)2 − 4 b: y = (x + 4)2 − 4 c: y = (x + 2)2 + 6 d: y = (x + 2)2 + 12

The line y = x + passes through (−3, 7) and is parallel to y = 4x − 1.

Can you me find the missing length. i attached an image.
