Question

Pls answer the question
Pls ans the first question

Answer 1

1. Sum of roots = 1/4
Product of roots = -1

Polynomial = x^2 - (sum of roots) x + product of roots
= x^2 - (1/4)x + (-1)
= x^2 -1/4x -1

To remove denominator multiply with 4
= 4x^2 -x -4

2. √2 , 1/3
Polynomial = x^2 - (√2)x +1/3

To remove denominator multiply with 3
3x^2 - 3√2x +1

3. 0, √5
Polynomial = x^2 - (0)x +√5
= x^2 +√5

If you satsfied mark it brainliest.
Can u pls tell me it is question of which class?
