Find the values of the polynomial for the given values of the variable.

-x2-5x-6

x=-3

x=-2

I got 0 for the first one and 0 for the second. Am I figuring them wrong? (and that is an x squared, not 2x)

-(-3)^2 -5(-3)-6

-(9)+15-6=0

Thanks!

you are right in both cases

-x^2-5x-6

=-(x^2+5x+6)

=-(x+2)(x+3)

notice if this had been an equation equal to zero,

x=-2 and x=-3 would have been solutions.

That is why both values gave you a zero answer.
