Answer 1

Answer:

value of polynomial is 12

Step-by-step explanation:

put the value of y=-1

(-1)*2-5(-1)+6

1+5+6

12

Answer 2

Answer :-

12

Step by step explanation :-

Given polynomial to us is y² - 5y + 6

So ,

$=> p(y) = y^2 - 5y + 6 \\=> p(y) = (-1)^2-5(-1)+6 \\=> p(y) = 1 +5 + 6 \\\bf => p(y) = 12$

Hence the required answer is 12.
