Solving Quadratic Equations

Let’s solve another way.

Completing the square for 1)Subtract c. 2)Divide by a. 3)Add to both sides of the equation. 4)Factor. 5)Take the square root of both sides. 6)Solve for x.

Solve by completing the square. This is called the Quadratic Formula. Any quadratic equation can be solved using this formula.

Solve using the quadratic formula.

Opposite of b, Opposite of b Plus or minus square root, Plus or minus square root b squared minus 4ac, b squared minus 4ac Over 2a, Over 2a
