Question

Find the value of the polynomial p(y) = y² – 5y + 6 at y = – 2​

Answer 1

Answer:

p(y) = y² – 5y + 6 at y = – 2

p(-2) = (-2)² - 5(-2) + 6

= 4 +10 +6

=20

PLS MARK ME BRAINLIEST!!

Answer 2

Answer:

p(y) = y² -5y + 6

=> p(-2) = (-2)² -5× (-2) +6

= 4 +10 + 6

= 20

so, the value of polynomial,p(y) at y = -2 is 20
