Determine the nature of the roots:
WebBut for finding the nature of the roots, we don't actually need to solve the equation. We can determine the nature of the roots by using the discriminant. The discriminant of the quadratic equation ax 2 + bx + c = 0 is D = b 2 - 4ac. The roots of quadratic equation formula is x = (-b ± √ (b 2 - 4ac) )/2a. So this can be written as x = (-b ± ... WebHere, discriminant is \(b^2 – 4ac\) and it is used to find the nature of the roots besides number of the roots. It is represented by D or Δ. What does a positive and negative …
