Answer:
1. Completing the square
2. Factorisation
3. Formula method
4. Graphical method
Answer:
- 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.
