    -2x^2+5x+3=0

    x=3

    x=-1/2

    Quadratic Function

  • 5 years ago

    If you get everything on one side you have:

    2x² - 5x + 3 = 0

    That's a second degree polynomial also called a "quadratic".

    To solve, you can just factor that as:

    (2x + 1)(x - 3) = 0

    That leads to two zeros:

    2x + 1 = 0

    2x = -1

    x = -1/2

    or

    x - 3 = 0

    x = 3

    Answer:

    x = -1/2 or x = 3

    2x² = 5x+3

    2x² - 5x - 3 = 0

    Use quadratic formula to find the zeros.

    x = [5 ± √(5² – 4·2(-3))] / [2·2]

     = [5 ± √49] / 4

     = [5 ± 7] /4

     = -0.5, 3

    If you move everything to the left hand side it is a quadratic

    2x^2- 5 - 3 = 0

    and the solutions are

    3 and - 1/2
