In need of some help! Thank you in advance. 100 points <3 1: Explain why the equation (x-4)^2-17=8 has two solutions. Then solve the equation to find the solutions. Show your work.

2: This is Josh’s solution for the equation x^2+4x+3=0:

x^2+4x+3=0
x^2+4x=-3
x^2+4x+4=-3+4
(x+2)^2=1
x+2=1
x=-1

Is Josh’s solution correct? Explain.

3:Use the quadratic formula to solve x^2-6x+7. Show your work. Then describe the solution. No work, no credit.
