Explain why the equation ( x - 4 )^2 - 28 = 8 has two solutions. then solve the equation to find the solutions. show your work

All quadratic quadratic have 2 solutions. so since this is a second power equation, it must also have 2.  x = 10 and x = -2.  you can get this by doing the arithmetic out to get the equation equal to zero. after that, you can solve by factoring the polynomial and solving for 0.
