Our next task is solving a quadratic equation. Just as with any algebraic equation such as x + 5 = 0, we will be able to say that x = something. This time however, x will not have just one solution, it will have up to two solutions!! In order to solve quadratics we must factor them! This is why we learned to factor!

Quadratic equations can have two, one, or no real-number solutions. Before you solve a quadratic equation, you can determine how many real-number solutions it has by using the discriminant. The discriminant is the expression under the radical sign in the quadratic formula. The discriminant of a quadratic equation ( b2 – 4ac) can be positive ...

Standard: Solve quadratic equations by inspection (e.g., for x2 = 49), taking square roots, completing the square, the quadratic formula and factoring, as appropriate to the initial form of the equation. Recognize when the quadratic formula gives complex solutions and write them as a ± bi for real numbers a and b.

The quadratic formula can be used to solve any quadratic equation. The value of the discriminant of a quadratic equation can be used to describe the number of real and complex solutions. The definition of absolute value (for any real numbers a and b, where b 0, if , then a = b or a = - b) is used in solving absolute value equations and ...
