Q:
Exhibit that our value -3 - 2* 2 is also a solution of our quadratic equation P(x) = x² + 6x + 1= 0. That is, evaluate P( -3 -2*2). The idea is to verify the solution (-3 - 2*sqrt(2)) for the equation x² + 6x + 1= 0. So we plug (-3 - 2*sqrt(2)) for x into the equation and perform the arithmetic to assure that the equation retains its validity.
