Answer 1

Step-by-step explanation:

1) 1 is the HCF

2) p(x) = ax² - bx + c

α+β = - (b/a) = -(-b)/a => b/a

σβ = c/a

1/α + 1/β = (α + β)/αβ

on substituting b/a ÷ c/a => bc/a²

7) cosec x = √2, then tan x = 1

9) 1/cot²x - 1/cos²x => sin²x/cos²x - 1/cos²x

=> (sin²x - 1)/cos²x => - cos²x/cos²x = - 1 ≠ 1
