Question

If p(x)=x2-5x -6, then find the values of p(1), p(2), p(0), p(-1), p(-3).​

Answer 1

The polynomial

p(x)=x

2

−5x−6

p(1)=1

2

−5(1)−6=1−5−6=−10

p(2)=2

2

−5(2)−6=4−10−6=−12

p(3)=3

2

−5(3)−6=9−15−6=−12

p(0)=0

2

−5(0)−6=0−0−6=−6

p(−1)=(−1)

2

−5(−1)−6=1+5−6=0

p(−2)=(−2)

2

−5(−2)−6=4+10−6=8

p(−3)=(−3)

2

−5(−3)−6=9+15−6=18
