9x^2 + 30x + ok = 0 x = (-30 +/- sqrt(900 - 4 * 9 * ok)) / (2 * 9) x1 = x2 To have in elementary terms one actual root, then sqrt(900 - 36k) could equivalent 0 0 = 900 - 36k 36k = 900 4k = a hundred ok = 25 5x^2 - 3x - ok = 0 x = (3 +/- sqrt(9 + 4 * 5 * ok)) / (2 * 5) x = (3 +/- sqrt(9 + 20k)) / (10) to be sure that x to have 2 actual roots, then 9 + 20k could be greater desirable than 0 (as a results of fact the sq. root of a unfavorable is an imaginary extensive type): 9 + 20k > 0 20k > - 9 ok > -9/20
