This interactive site is excellent in giving practice
solving linear equations with one variable.

This interactive site gives practice
solving quadratic equations. It uses the quadratic formula,
and if you input values for a, b, and c for which the
expression under the radical (b^2 - 4ac) is less than
0, the quadratic formula will return a complex number
(which is beyond the scope of this course). For our use,
make sure b^2 - 4ac is not less than zero, and you will
obtain the desired result.
