WEBdefinitions, explanations and examples for elementary and advanced math topics. Purple Math – A great site for the Algebra student, it contains lessons, reviews and homework guidelines.
WEBAs in all subjects, it is important in mathematics that when a word is used, an exact meaning needs to be properly understood. This is where we will begin. When you were young an important skill was to be able to count your candy to make sure your sibling did not cheat you out of your share. These numbers can be listed: {1,2,3,4,...}.

WEBQuadratic Formula To solve ax2 + bx+ c= 0, a6= 0, use : x= 2b p b 4ac 2a. The Discriminant The discriminant is the part of the quadratic equation under the radical, b2 4ac. We use the discriminant to determine the number of real solutions of ax2 + bx+ c= 0 as such : 1. If b2 4ac>0, there are two real solutions. 2. If b2 4ac= 0, there is one ...
