19 x a x a x b = 19a2b
(4x - t2)= [(2√x)2 - t2] (This is now the difference of squares)= (2√x - t)(2√x + t)
n2 - 100t write t = (√t)2 = n2 - (10√t)2 = (n - 10√t)(n + 10√t)
That doesn't factor neatly. Applying the quadratic equation, we find two real solutions: (19 plus or minus the square root of 1441) divided by 2t = 28.480252896102307t = -9.480252896102307
