Quadratic Equations
- The standard form of a quadratic equation is ax^2 + bx + c = 0, where a, b, and c are constants and a ≠ 0.
- The condition for 'a' in the standard form of a quadratic equation is a ≠ 0, which means 'a' should not be equal to zero.
- x^2 + 2x + 1 = 0 is a quadratic equation, but x^2 + 2x + 1 = 2x is not a quadratic equation, as it does not equate to zero.
