<pre>

Find the roots of the quadratic equation


    5x^2 - 13x - 6 = 0


using quadratic formula


    {{{x[1,2]}}} = {{{(13 +- sqrt(13^2 + 4*5*6))/(2*5)}}} = {{{(13 +- sqrt(289))/10}}} = {{{(13 +- 17)/10.


The roots are  3 and  {{{-4/10)}}} = -{{{2/5}}}.


Hence, factored form is   5x^2 - 13x - 6 = {{{5*(x-3)*(x-(-2/5))}}} = (x-3)*(5x+2).   <U>ANSWER</U>
