    Answer: B. 2=3x+10x^2

    Step-by-step explanation:

    The expression means the quadratic function equation.

    B = 10x^2 + 3x - 2 = 0

    the equation is [-b ±√ (b^2 - 4ac) ]/2a

    b should be + 3 to become - 3 when it is plugged into the equation, and 'a' should be 10, and c should be - 2.
