Question

Find the value of polynomial p(x)=xsquare2 -9 at x=3 and x=-3

Answer 1

Answer:

the value of polynomial when x = 3 and x = -3 is 0

Step-by-step explanation:

given polynomial: p(x) = x² - 9

when x = 3,

⇒p(x) = x² - 9

⇒p(3) = (3)² - 9

⇒p(3) = 9 - 9 = 0

when x = -3,

⇒p(x) = x² - 9

⇒p(-3) = (-3)² - 9

⇒p(-3) = 9 - 9 = 0

therefore the value of polynomial when x = 3 and x = -3 is 0
