Some of the steps for completing the square to solve
x2 + 5x = 2 are shown.

x2 + 5x = 2

x2 + 5x + (StartFraction 5 Over 2 EndFraction) squared = 2 + (StartFraction 5 Over 2 EndFraction) squared

(x + StartFraction 5 Over 2 EndFraction) squared = StartFraction 33 Over 4 EndFraction

Which are solutions of x2 + 5x = 2?
