Answer 2

Answer:

1) √6

2) b) 2x²+5x = (x+1)x + 1

3) p(2) = 4a+2b+c

Step-by-step explanation:

Hii Meena ✌

(1) kx² + (√3 - √2)x - 1 = 0

x = 1/√3 is a root of given equation,

So, when we put x=1/√3 in equation,

It satisfies the equation.

So, equation becomes

k (1/√3)² + (√3 - √2)(1/√3) - 1 = 0

=> k(1/3) + (√3-√2)/3 - 1 = 0

=> k/3 + (√3/√3) - (√2/√3) - 1 = 0

=> k/3 + 1 - (√2/√3) - 1 = 0

=> k/3 = √2/√3

=> k = √2/√3 × 3

=> k = √2/√3 × (√3×√3)

=> k = √2 × √3

=> k = √(2×3)

=> k = √6

100% CORRECT ✔️✔️
