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
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
