e.g. If the highest degree of all variables put together is 2, then it is called quadratic and if it is 3, then it is a cubic function.Factoring is a reverse process To find x2, substitute the value you found for x1. Substitution Evaluates an expression by substituting for given variables, then simplifying. Check This Out

Once again, it is straightforward to check these solutions by plugging them back into the quadratic equation. The correct choices for m and n are -1 and 5, and the polynomial factors are:(x – 1)(x + 5)Now that we've gotten some practice with the friendlier varieties of quadratic Thus, the solutions of the quadratic equation are x = 2 and x = 4. So we know that a and c must be factors of 25. http://www.onlinemathlearning.com/factor-trinomials-unfoil.html
