    Hello,

    You have the two roots of the equation.

    The most direct way is to plug in the equation the values of the roots to solve for a, b and c..

    Another way consists in remembering that if m and n are the roots of the trinomial, then m+n=b and mn=c


    Another way again is to know that if m and n are the roots of a trinomial, then it's equal to (x-m)(x-n)
