Algebra 2

please help i seriously don't understand any of these!!

solve by factoring:

1.x^3-12x = x^2

simplify

1.4c/12c^5

2. a^2x/a

3. x^3y^4/2 x^2y^6

  1. you seriously need to do some effort.

    The first, put it in the form
    x^3-x^2-12x=0
    x(x^2-x-12)=0
    x(x-4)(x+3)=0
    x=0;4;-3

    then I will do one of the others.

    3) change it to read

    x^3/x^2 * y^4 /2y^6

    x*1/2y^2
    or x/2y^2
