Solve for the value of z
z(z-6)=0​

The answer is D.

Explanation:

I decided to start with 6 because it seemed to be the easiest. So you would out 6 in the place of ‘z’

6 ( 6 - 6 ) = 0

Here you would do the parentheses first

6 ( 0 ) = 0
6 * 0 = 0
0 = 0

You’re not done bc it could be both 6 and -6 So input where ‘z’ is and you should get

-6 ( -6 - 6 ) = 0
-6 ( -12 ) = 0
72 doesn’t equal 0

Hope this helped
