Question

If P(x) = x²-5x-6 then P(-1) =​

Answer 1

Answer:

Given, p(x)=x

2

−5x−6

⇒p(3)=3

2

−5×3−6

⇒p(3)=9−15−6

⇒p(3)=−12

Answer 2

Answer:

0

Step-by-step explanation:

p(x) = x²-5x-6

p(-1) = (-1)² - (5 X -1) - 6

p(-1) = 1 - (-5) - 6

p(-1) = 1 + 5 - 6

p(-1) = 6 - 6

p(-1) = 0

Hence -1 is the zero of the polynomial p(x) = x² - 5x - 6
