Question 703841
Use the quadratic formula to solve for x


{{{x = (-b+-sqrt(b^2-4ac))/(2a)}}}


{{{x = (-(5)+-sqrt((5)^2-4(1)(10)))/(2(1))}}} Plug in {{{a = 1}}}, {{{b = 5}}}, {{{c = 10}}}


{{{x = (-5+-sqrt(25-(40)))/(2)}}}


{{{x = (-5+-sqrt(-15))/2}}}


{{{x = (-5+sqrt(-15))/2}}} or {{{x = (-5-sqrt(-15))/2}}}


{{{x = (-5+i*sqrt(15))/2}}} or {{{x = (-5-i*sqrt(15))/2}}}
