2x² 3x +5 = 0 delta: (3)²  4*5 *2 = = 9  40 = 31 ~ Are you sure the equation is 2x² 3x+5 =0 not 2x²3x5 =0 ?

well it was 2x^23x=5, that translates to 2x3x+50 doesn't it? :o

so, If is 2x² 3x +5=0 delta = b² 4*a*c = 31 and \[(b \pm \sqrt{\Delta})\div 2 *a =\] \[((3)\pm \sqrt{31}) / 4 =\] \[(3\pm i \sqrt{31} )/ 4\] \[x' = (3+ i \sqrt{31}) /4\] \[x'' = (3 i \sqrt{31}) /4\]
