find the values of each of the following polynomials for the given values of the variable.
for x=-3 and for x=-2
-x^2-5x-6

how do i do the above i am not sure but have an idea can someone help?

    All you have to do is plug x into the polynomial. For x=-3, you would have -(-3)^2-5(-3)-6. Simply that to get your solution (which should be just a number). Then, plug in -2 for the second part, simplify, and you're done.

    how is this?

    -(-3^2)-5(-3)-6=
    -9+15-6=18 (18 is the answer?)

  • math - algebra -

    << -9+15-6=18 >> ??

    how did you get 18 for that?

    -9+15-6
    15-9-6
    = 15-15
    = 0
