Answer:
I'm assuming the equation is:
2x^2 -10x +7 = 0
x = (-b +- sqr root (b^2 - 4ac)) / 2a
x = (--10 +-sqr root (100 -4*2*7)) / 4
x = (10 +- sqr root (44)) / 4
x1 = (10 + 6.6332495807
) /4
x1 = 16.6332495807 / 4
x1 = 4.1583123952
x2 =(10 - 6.6332495807
) /4
x2 = 3.3667504193 / 4
x2 = 0.8416876048
