p in (-oo:+oo)
1/2 = (5*p-8)/12 // - (5*p-8)/12
1/2-((5*p-8)/12) = 0
(-1*(5*p-8))/12+1/2 = 0
(-1*2*(5*p-8))/(2*12)+(1*12)/(2*12) = 0
1*12-1*2*(5*p-8) = 0
28-10*p = 0
(28-10*p)/(2*12) = 0
(28-10*p)/(2*12) = 0 // * 2*12
28-10*p = 0
28-10*p = 0 // - 28
-10*p = -28 // : -10
p = -28/(-10)
p = 14/5
p = 14/5
