Answer 1

The solution of a quadratic equation is given by the following quadratic formula

x = (-b ± √(b² - 4ac)) / 2a

For this case a = 5, b = 20, c = 32

x = (-20 ± √(20² - 4(5)(32))) / 2(5)

x = (-20 ± √(400 - 640)) / 10

x = (-20 ± √(-240)) / 10

x = (-20 ± i√(240)) / 10

x = -2 ± i√(240/100)

x = -2 ± 1.55i)
