Using the quadratic formula to solve x squared plus 20 is equal to 2 x , what are the values of x ?

Rewrite the equation in standard form: x² − 2x + 20 = 0. Using the quadratic formula, the discriminant is (−2)² − 4(1)(20) = −76, so the roots are [2 ± √(−76)]/2 = 1 ± √19 i. Therefore, the values are 1 plus or minus square root of 19 i, choice D.
