Definition of Quadratic Equations
Quadratic Equation is an equation which contains at least one squared term. It can be defined in the form of rx^2 + dx + z = 0. Where a, b and c are constants and ‘x’ is an unknown variable.
- If p+ √q is a root of a quadratic equation, then its other root is p- √q
- When D ≥ 0, then rx^2+ dx + z can be expressed as a product of two linear factors.
- If α and β are the roots of rx^2+ dx + z, then we can write it as: x^2 – (α + β)x + α β = 0
