what is a sum of quadratic polynomial & product of quadratic polynomial .

Please give ans in a proper way . ​

Answer 1

Answer:

• sum of cubic polynomial is α+β+¥ = -b/a
• product = α.β.¥ = -d/a
• sum of quadratic polynomial is α.+β = -b/a
• product = c/a

Answer 2

⟹ (α+β+γ) = −B/A

⟹ (αβ+βγ+γα) = C/A

⟹ (αβγ) = −D/A
