The solution set for -2x^2+12x=0
natita [175]

Answer:

{0,6}

Step-by-step explanation:

-2x^2+12x = 0

Factor out a -2x

-2x(x-6) =0

Using the zero product property

-2x = 0   and x-6=0

-2x = 0

Divide by -2

-2x/-2 = 0/-2

x=0  

x-6=0

Add 6 to each side

x-6+6 =0+6

x=6

The solutions are 0 and 6
