The answer is the option A.

x=(5± $\sqrt33$ )/4

Step-by-step explanation:

The quadratic formula has the following form for a quadratic equation ax²+bx+c:

x=(-b± $\sqrt{b^{2} -4ac}$ ))/(2a)

We apply the quadratic formula and we obtain:

x=(-(-5)± $\sqrt{5^{2} -4(2)(-1)}$ ))/(2(2))

x=(-(-5)± $\sqrt{25 +8}$ ))/(4)

x=(-(-5)± $\sqrt{33}$ ))/(4)
