Solving quadratic equations using the Quadratic Formula.

Link to section in online textbook.

First, watch the video below to learn how to use the Quadratic Formula to solve quadratic equations. You can use the notes here to follow along with the video and record your thoughts. Remember: this method will always work, but may not be the easiest method.

Now practice solving quadratic equations with the quadratic formula.

Solve the quadratic below.

$\sage {problemDisplay11} = 0$

Smaller solution: $x = \answer [tolerance=0.05]{\sage {solution11[0]}}$

Larger solution: $x = \answer [tolerance=0.05]{\sage {solution11[1]}}$

Solve the quadratic below.

$\sage {problemDisplay12} = 0$

Smaller solution: $x = \answer [tolerance=0.05]{\sage {solution12[0]}}$

Larger solution: $x = \answer [tolerance=0.05]{\sage {solution12[1]}}$

Solve the quadratic below.

$\sage {problemDisplay13} = 0$

Smaller solution: $x = \answer [tolerance=0.05]{\sage {solution13[0]}}$

Larger solution: $x = \answer [tolerance=0.05]{\sage {solution13[1]}}$
