Multiplies to _ and adds to _ calculator

If you have the sum of two numbers as well as the product those numbers, you can use this online calculator to calculate the actual numbers for you:


This is especially useful for factoring trinomials, such as x2+7x+12, by entering the coefficients into the calculator. For example, if you make X*Y=12 and X+Y=7, then you find that X=5 and Y=-12. You can then rewrite the trinomial in its factored form, (X+4)(X-3).
