Question

Find the polynomial function with the following roots,

-3 of multiply 2, and 5.
PLEASE SHOW WORK!

Answer 1

Ok so if it has roots of -3 and 5 it should be divisible by (x+3) and (x-5) and it is also divisible by 2

Therefore it is divisible by 2(x+3)(x-5)

If you multiply that out you get 2x^2 -2x -15
