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 = 2 x = 8

For this case we have the following equation:

We make the following change of variables:

We have then:

Then, using the quadratic formula we have:

Solution 1:

Solution 2:

Finally, returning the change we have:

Solution 1:

Solution 2:
