Question
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.
