Question

Hello humans ~
explain how can we find real roots of a quadratic equation ​

Answer 1

- For a quadratic equation ax2 + bx + c = 0, The roots are calculated using the formula, x = (-b ± √ (b² - 4ac) )/2a.

- Discriminant is, D = b2 - 4ac. If D > 0, then the equation has two real and distinct roots.

Answer 2

1. Completing the square

2. Factorisation

3. Formula method

4. Graphical method
