When dealing with imaginary numbers as roots of a polynomial, you will see that they always occur in conjugates. So the other root that goes with this one is -3 - i.  This will always be the case.

Evaluate: 2(1/4) + 2/5 ÷ (-1/2) - 1/4

⇛9/4 + 2/5 ÷ (-1/2) - 1/4

Take the LCM of the 4 and 5 is 20.

Again, 2 and 4 is 4.

⇛[(54+8)/20] ÷ [(-2 - 1)/4]

⇛62/20 ÷ (-3/4)

⇛62/20 × 4/-3

⇛62/{5*(-3)}

⇛62/-15.
