Solving quadratic equations using the Quadratic Formula.

Link to section in online textbook.

First, watch this video to learn how to solve quadratic equations using the Quadratic Formula. 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: $x = \answer [tolerance=0.05]{\sage {solution13[1]}}$
