Solve these equations for x by factoring:

1) x(x-4)=12
2) 2x^3+50x=20x^2
3) 2x^2+x-6=0

Thank you for all your help!!!!

    Pre calculus? This is stock Algebra II.

    put the equations in the form of

    ax^2+bx+c=0 then factor.

    for instance, c is already in that form.

    2x^2+x-6=0
    (2x-3)(x+2)=0
    x= 3/2 x=-2

    do the others the same method.
