Hi, Attempting to solver for x: y=5/6 * x * (2x^2 +27x +91)

y=(5/6) x*(2x^2 +27x +91) .....factor 2x^2 +27x +91 2x^2 +27x +91 =2x^2 +14x+13x +91 =(2x^2 +14x)+(13x +91) =2x(x +7)+13(x +7) =(x + 7) (2 x + 13) y=(5/6) x*(x + 7) (2 x + 13) so, you have set y=0 (5/6) x*(x + 7) (2 x + 13) =0 equal each factor to 0 (5/6) x =0 => x=0 (x + 7) = 0 => x=-7 (2 x + 13) =0 => x=-13/2
