I need to solve these equations :

1) 5w^2 - 5w = 0

2) 2x^2 + 15x = 0

3) -32y^2 - 24y = 0

4) 6h^2 = 3h

5) -42z = 14z

6) -12p^2 = -30p

  • Algebra - ,

    They are all of the same type and require factoring using a common factor routine

    I will do one of them, you try the rest

    #2
    2x^2 + 15x = 0
    x(2x+15) = 0
    then x = 0 or 2x+15=0

    x = 0 or x = -15/2
