Solve using factoring, completing the square, or the quadratic formula.
s%5E2%2B3s%2B5
Enter the exact answers in increasing order.
using method of completing the square
s%5E2%2B3s%2B5=+0
s%5E2%2B3s= -5
add %283%2F2%29%5E2 to both sides
s%5E2%2B3s%2B%283%2F2%29%5E2 = -5%2B%283%2F2%29%5E2
s%5E2%2B3s%2B%283%2F2%29%5E2 = -5 + 9%2F4
s%5E2%2B3s%2B%283%2F2%29%5E2 = -11%2F4
%28s%2B3%2F2%29%5E2 = -11%2F4
s%2B3%2F2 = +- sqrt%28-11%2F4%29
s%2B3%2F2 = +- sqrt%28-11%29%2F2
since sqrt%28-1%29 = i
s%2B3%2F2 = +- %28i%2Asqrt%2811%29%29%2F2
s = -%28i%2Asqrt%2811%29%29%2F2+-+%283%2F2%29 or %28i%2Asqrt%2811%29%29%2F2+-+3%2F2
s = -%28i%2Asqrt%2811%29%2B3%29%2F2 or %28i%2Asqrt%2811%29-+3%29%2F2
