Find b^2 - 4ac and the number of real solutions to equation.

-3x^2+7x=0

  • algebra -

    The equation is in the form
    ax^2 + bx + c = 0
    -3x^2 + 7x = 0

    So, a = -3, b = 7, and c = 0

    b^2 - 4ac = 49 - 0 = 49

    The square root of a positive number is a real number, so there are 2 real solutions by the quadratic formula.
