Question:
what is the formula to find the roots alpha and beta
Answer:
Let the quadratic equation is
ax2 + bx + c = 0
Let α and β are the roots of the quadratic equation
Now,
α + β = -b/a .............1
and αβ = c/a
Now (α - β)2 = (α + β)2 - 4αβ
=> α - β = √{(α + β)2 - 4αβ} .......2
Solve eqaution 1 and 2, we will get the value of α and β
