What is the solution of the equation (x – 5)2 + 3(x – 5) + 9 = 0? use u substitution and the quadratic formula to solve.
x = startfraction negative 3 plus-or-minus 3 i startroot 3 endroot over 2 endfraction
x = startfraction 7 plus-or-minus 3 i startroot 3 endroot over 2 endfraction
x = 2
x = 8

Option 2 -  

Step-by-step explanation:

Given : Equation

To find : What is the solution of the equation ?

Solution :
