Second-Degree Equation

Second-Degree Equation

Equation in which there is at least one squared variable or a product of variables.

  • Equation in which the unknown has an exponent of 2.
  • The general form of the second-degree equation in one variable is Ax² + Bx + C = 0.
  • For this type of equation, the term unknown is used instead of the term variable, since the values of the unknown do not change.


The equation 2\({x^2}\) – 5x + 2 = 0 is a second-degree equation in one variable.
The values of the unknown x are {1/2, 2}.
