then the two roots of x are: \(\huge{x=\frac{b \pm \sqrt{b^24ac}}{2a}}\)

Use the quadratic foumula \[x_1 =\frac{ b + \sqrt{b^24ac}} {2a}\] \[x_2 =\frac{ b  \sqrt{b^24ac}} {2a}\]

You have imaginary roots. Is that what you're worried about?

Why? Is it a physics problem and you are supposed to have real roots? Because there is nothing wrong with the quadratic formula. Double check your coefficients

because with the coefficients, its (4)^24(2)(5) , in the square root right?

no i i mixed up the coefficents in the original question. i was given a=2;b=4;c=5

ok, \(\huge{x=\frac{4 \pm \sqrt{24}}{4}}=\frac{4 \pm 2\sqrt{6}}{4}=\frac{2\pm i\sqrt{6}}{2}\)
