Solve incomplete quadratic equations

In this video I will explain how solve incomplete quadratic equations. Remember that an equation of the second degree is an equality.

In the case of an incomplete quadratic equation one of the factors b or c will be zero. Recall that the a will always be nonzero (in both complete quadratic equations and incomplete quadratic equations).

In order to solve an incomplete quadratic or quadratic equation we can do two things:

• use the formula of quadratic equations complete:

• use other methods like draw common factor or make a square root (in the video you will see examples to understand it better)

Also, it should be noted that some incomplete quadratic equations have no solution.

If you want to practice what you learned in today's lesson on the incomplete equations you can do the printable exercises with their solutions that I have left you on the web. I hope they help you!
