solve this quadratic equation using the quadratic formula. 2x2 - 10x + 7 = 0
2x^2 - 10x + 7 = 0 2(x - 5/2)^2 - 25/2 + 7 = 0 2(x - 5/2)^2 = 11/2 (x - 5/2)^2 = 11/4 x - 5/2 = ±sqrt of 11/2 x = ±sqrt of 11/2 + 5/2

2x^2 - 10x + 7 = 0
2(x - 5/2)^2 - 25/2 + 7 = 0
2(x - 5/2)^2 = 11/2
(x - 5/2)^2 = 11/4
x - 5/2 = ±sqrt of 11/2
x = ±sqrt of 11/2 + 5/2
