Question

find the value of the polynomial y2-5y+6 at y=-2 .mention the steps along with your answer​

Answer 1

P(2)=2×2-5×2+6

=4-10+6

=4-4

=0

P (-2)=(-2)×2-5×(-2)+6

=(-4)+10+6

=-4+10+6+6

=12

Answer 2

Answer:

12

Step-by-step explanation:

y2 - 5y + 6

where y = -2

y(-2) = -2×2 - 5×-2 + 6

y(-2) = -4 + 10 + 6

thus,

16-4

12 ans
