Question 207069
<font face="Garamond" size="+2">


All quadratic equations have 2 solutions.  So if you are only given one, the other one must be identical -- that is to say *[tex \Large x = 10] and *[tex \Large x = 10]


That means the two factors of your trinomial must be:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ (x - 10)(x - 10)  = 0]


Apply FOIL and the result will be the desired trinomial.
