What is the solution of the equation (x – 5)2 + 3(x – 5) + 9 = 0? use u substitution and the quadratic formula to solve.

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
