4x^3-2x^2+x-2

Predict the number of complex roots and explain how you got it

Step-by-step explanation:

4x^3-2x^2+x-2

4x³-2x²+x-2=0

2x²(x-2)+1(x-2)=0

(2x²+1)(x-2)=0

x-2 = 0          2x²+1 =0

x=2                   2x² =-1

                         x² = -1/2

                         x =√-1/2

x = √-1/2.   2
