The equation given above is written here below with all the terms transposed to only one side of the equation.
2x² + 3x + 8 = 0
The quadratic formula used for the determination of the roots is,
x = (-b + / - sqrt (b² - 4ac)) / 2a
In the quadratic equation above, we have the numerical coefficients.
a = 2
b = 3
c = 8
Substituting the known values,
x = (-3 + / - sqrt (3² - 4 (2) (8)) / (2) (2)
x = - 0.75 + 1.854i and x = - 0.75 - 1.854i
By the calculated roots above, it is known that the roots are imaginary.
