divide by 12
x^2 + (11/12)x = 5/12
add the square of half the middle term coefficient
x^2 + 11x/12 + 121/576 = 5/12 + 121/576
(x + 11/24)^2 = 361/576
x+ 11/24 = ± √361/24
x = (-11 ± √361)/24
BTW, just noticed below that bobpursley did the same question for you yesterday
How silly of me not to notice that √361 = 19
sometimes it happens that 2*2=5
