Solve :- x2 -(7 - i) x + (18 - i) = 0 over C.

ANURAG.

x2 – (7 – i) x + (18 – i) = 0

On comparing the given equation with general equation ax2 + bx + c = 0, we get a = 1, b = – (7 – i)  and c = 18 – i

We shall first find

But 2ab = – 10, so a and b must be of opposite signs.

Substituting either of these values in (i), we get

Hence, roots of the given equation are 4 – 3i and 3 – 3i
