Question

3. Find the value of the polynomial y2-5 y+6 at
(1) y = 0 (2) y = -1​

Answer 1

Answer:

-25

y=0 & y=-1

y=0 & y=-1(0×2-5)×(-1+6)

y=0 & y=-1(0×2-5)×(-1+6)-5×5

y=0 & y=-1(0×2-5)×(-1+6)-5×5-25

Answer 2

Answer:

1. y = 0

y²-5y +6

(0)² - 5(0) + 6

0 - 0 +6

0+6

6

2. y =(-1)

y² - 5y + 6

(-1)² - 5(-1) +6

1 - (-5)+ 6

1+ 5+6
