Which equation can be solved using the expression StartFraction negative 3 plus-or-minus StartRoot (3) squared + 4 (10) (2) EndRoot Over 2 (10) EndFraction for x?
10x2 = 3x + 2
2 = 3x + 10x2
3x = 10x2 – 2
10x2 + 2 = –3x

Rewrite the equation in standard form ax^2 + bx + c = 0. The formula given is x = (-3 ± sqrt(3^2 + 4·10·2)) / (2·10), so a = 10, b = 3, c = -2.

Thus the equation is 10x^2 + 3x - 2 = 0, which matches the option
2 = 3x + 10x2.
