| http://www.hostsrv.com/webmab/app1/MSP/quickmath/02/pageGenerate?site=quickmath&s1=equati... | ||
| Interactive applet. After entering equation the user has the following options to choose from (one-stop-shopping). More importantly it shows full solutions for whatever is selected should the user wish to view them. -Factors -Solves f(x)=0 by factoring, quadratic formula, completing the square -Rewrites in vertex form -Concavity -x-intercepts -y-intercept -Axis of symmetry -Vertex -Plot -Discriminant -How many zeros ( http://www.hostsrv.com/webmab/app1/MSP/quickmath/02/pageGenerate?site=quickmath&s1=equati... ) | ||
