Question

from the quadratic equation whose roots are 2 and 1/2 ​

Answer 1

Answer:

you include repeated or complex roots then yes quadratic equations have two roots. If you don't include repeated or complex roots then no quadratic equations can have up to a maximum of two roots. They might have zero, one or two roots.

α + β = - ba and αβ = ca.

⇒ x2 + bax + ca = 0 (Since, a ≠ 0)

⇒ x2 - (α + β)x + αβ = 0, [Since, α + β = -ba and αβ = ca]
