Solution for (3/6x+2)(36x^2-4/7x) equation: 


x in (-oo:+oo)

((3/6)*x+2)*(36*x^2-((4/7)*x)) = 0

((3/6)*x+2)*(36*x^2+(-4/7)*x) = 0

(1/2*x+2)*(36*x^2-4/7*x) = 0

36*x^2-4/7*x = 0

4*x*(9*x-1/7) = 0

9*x-1/7 = 0 // + 1/7

9*x = 1/7 // : 9

x = 1/7/9

x = 1/63

4*x*(x-1/63) = 0

4*x*(1/2*x+2)*(x-1/63) = 0

( 1/2*x+2 )

1/2*x+2 = 0 // - 2
