Roots of Quadratic Equations
Basic terms of Quadratic Equation
If `ax^2 + bx + c = 0` be a quadratic equation and `alpha` , `beta` are the roots,
- Number of roots = 2 i.e. degree of equation.
- Both roots will satisfy the equation.
- `alpha` + `beta` = `-b/a` and `alpha` `beta` = `c/a`
Factorization of Quadratic Equation
- Start with constant term
- Factorize the constant term
- After factorizing, choose that pair whose: addition or subtraction gives coefficient of x
