Question

Give the basic polynomial function that has the following roots:

5, -2, -1

Answer 1

Just use the 0 Product property.
The first factor is going to be (x-5), because then 5 is a solution.
The second is (x+2), because then -2 is a solution.
So so far we have (x-5)(x+2) = 0.
Now add on the last factor to the left side. If you want, you can expand.

Answer 2

thank you soo much your a life saver
