Question

i need help on equations that are equivalent to 0
the problem I'm stuck on is 3x(x+6)=0

Answer 1

Use the distributive property. 3x*x+ 3x*6=0

Answer 2

^ That's redundant if you're trying to find what x =

Answer 3

You would get 3x^2 + 18x=0
Subtract 18x and you get 3x^2=-18x
Divide out the x and you get 3x=-18
Divide out the 3 and you get x=-6

Answer 4

That's completely unnecessary and only half right.
You already have your equation in factored form, just equate x to 0
