Alebra problem help!?

use the quadratic formula to solve the equations.

2-2x=3x^2

  • use the quadratic formula to solve the equations.

    2 - 2x = 3x^2

    3x^2 + 2x - 2 = 0

    x = [- b ± √(b^2 - 4ac)]/2a

    a = 3, b = 2, c = - 2

    there you go...make a contribution...you can do it.

    [x = [- 2 ± 2√7]/6 = [- 1 ± √7]/3]

  • Rearrange to 3x^2+2x-2=0

    This then fits the model ax^2+bx+c=0

    So a=3, b=2, c=-2.

    Substitute into the quadratic formula which is

    x= [-b +/- sqr rt (b^2 - 4ac)]/2a

    so you get x = [-2 +/- sqr rt (2^2 -4x3x-2)]/(2x3)

    x = (-2 +/- 5.29)/6

    so x = 0.549 or x = -0.8819
