Answer:
x= -4, -3, 3
Step-by-step explanation:
You must factor this equation.
Once you factor, you get (x+4)(x-3)(x+3)
Set this equal to 0 and solve.
You get -4,-3, and 3.
To find the output when you know the input, just plug the input into the function.
x+21=4+21=25
The output is 25.
Hope this helps!
