Nonlinear Equations in One Variable

Parameter questions for nonlinear equations often use roots, discriminants, squared forms, radical equations, or factored forms.

Least you need to know

  • A quadratic has exactly one real solution when its discriminant is 0.
  • Roots can be connected to coefficients using sum and product relationships.
  • A proposed solution can be substituted into a radical equation to solve for a parameter.

Key notation

  • $b^2-4ac$ — The discriminant of a quadratic equation

Worked example

  • Translate the stated solution condition into an equation involving the parameter.
  • Solve for the parameter and check restrictions if needed.

Common mistakes

  • A squared equation can have two solutions.
  • Radical equations may require checking the original equation.

How to recognize it

  • The problem asks for a parameter related to roots, solutions, or the number of solutions.
