  1. 9.2 Notes Solving Quadratic Equations by Finding Square Roots

  2. Warm-up 1) 2) 3)

  3. Objective: • solve a quadratic equation by finding square roots Key terms: - quadratic equation - leading coefficient

  4. Solve Quadratic Equations A quadratic equation in standard form looks like this: a is the leading coefficient When b = 0 then it looks like this: One way to solve an equation in this form is by finding square roots of each side.
