Question 1187663
 {{{f(x)=x^3+x^2-17x+15}}}......factor
 {{{f(x)=x^3-3x^2+4x^2-12x-5x+15}}}
 {{{f(x)=(x^3-3x^2)+(4x^2-12x)-(5x-15)}}}
 {{{f(x)=x^2(x-3)+4x(x-3)-5(x-3)}}}
{{{f(x) = (x - 3) (x^2 + 4 x - 5)}}}
{{{f(x) = (x - 3) (x^2 -x+ 5 x - 5)}}}
{{{f(x) = (x - 3) ((x^2 -x)+ (5 x - 5))}}}
{{{f(x) = (x - 3) (x(x -1)+ 5(x - 1))}}}
{{{f(x) = (x - 3) (x - 1) (x + 5)}}}

solutions: {{{x=3}}},{{{x=1}}},{{{x=-5}}}
