(x*(x+2))/2 = 24*x^2 // - 24*x^2
(x*(x+2))/2-(24*x^2) = 0
(x*(x+2))/2-24*x^2 = 0
(x*(x+2))/2+(-24*2*x^2)/2 = 0
x*(x+2)-24*2*x^2 = 0
2*x-47*x^2 = 0
2*x-47*x^2 = 0
x*(2-47*x) = 0
2-47*x = 0 // - 2
-47*x = -2 // : -47
x = -2/(-47)
x = 2/47
x*(x-2/47) = 0
(x*(x-2/47))/2 = 0
(x*(x-2/47))/2 = 0 // * 2
x*(x-2/47) = 0
