Question 297398
{{{x=(8+-sqrt(64-4*1*14))/(2)}}}

{{{x=(4+-sqrt(2))}}}

steps-

once you follow the steps of the quadratic formula and reduce the {{{(sqrt8))}}} you can reduce the radical to {{{(2sqrt2))}}} and then eliminate the 2 outside the radical because the denominator of the formula is 2 also.  Hope this helps
