Answer:
x=0 or x=7
Step-by-step explanation:
Explanation:
The format of this queston is already in factored form. This makes it quite easy to solve for
x. They key to this is to know that anything multiplied by 0 is 0.
We have two things multiplied by each other:
x multiplied by (x−7) = 0
So, this means, that if either term is equal to zero, the whole equation will equal to zero.
The first term is just x, so x = 0 is the first solution.
The second term is (x−7).
We need to set that equal to zero and solve for x.
x − 7 = 0
x = 7 which is our second solution.
To check, plugging back into x (x−7) = 0 :
For: x = 0
0 (−7)= 0
0 = 0
so it works.
For
x = 7
7 (7−7) = 7 ( 0 ) = 0
which also works.
