Best ResponseYou've already chosen the best response.0I think that they are wrong, please apply this formula: \[\Large x = \frac{{  b \pm \sqrt {{b^2}  4 \times a \times c} }}{{2 \times a}}\] where: a=1, b=5, and c=6

Best ResponseYou've already chosen the best response.0more explanation: that formula above, is referring to the standard form of the quadratic equation: \[\Large a{x^2} + bx + c = 0\]

Best ResponseYou've already chosen the best response.0I'm sorry, no, since you have to find two numbers whose sum is 5, and whose product is 6. Now the sum of your numbers is: 2+3=5 which is different from 5
