Question

The non trivial values of (a, b) such that the roots of the equation x2 + ax + b = 0 are a and b are
1) 2, -1
2) 1, -2
3) 3, 2
4) 12,1​

Answer 1

Answer:

hi

Step-by-step explanation:

Answer 2

Answer:

1,-2

Step-by-step explanation:

Roots of x^2

+ax+b=0 are a and b

Sim =a+b=−a

⇒ 2a+b=0.....(1)

Product =ab=b

⇒ ab−b=0

⇒ b(a−1)=0

⇒ either b=0 or a=1

at b=0,, a=0

at a=1, b=−2 (from (1))

⇒ Non trivial values of (a,b) is (1,−2)
