Question 84079
 find the values of each of the polynomials for the given values of the variable
-x^2 - 5x - 6, 
:
x = -3; substitute -3 for x in the above equation:
-(-3^2) - 5(-3) - 6 =
-(+9) - (-15) - 6 = ;
-9 + 15 - 6 = ; minus a minus = a plus
+15 - 15 = 0
:
x = -2; substitute -2 for x in the same equation
-(-2^2) - 5(-2) - 6 =
-(+4) - (-10) - 6 =
-4 + 10 - 6 = 
-10 + 10 = 0
