if (x-1) is a factor then,
x-1=o
x=1
now put the 1 in your givien equation
4x+3jx+2*2-1
=4×1+3×1×j+4-1
=4+3j+3
now this equation must be equal to 0
so, 4+3j+3=0
7+3j=0
7=-3j
j=-7/3
x-1=o
x=1
now put the 1 in your givien equation
4x+3jx+2*2-1
=4×1+3×1×j+4-1
=4+3j+3
now this equation must be equal to 0
so, 4+3j+3=0
7+3j=0
7=-3j
j=-7/3
hope this will help you
