Question

Solve : x2- 5i x-6 = 0​

Answer 1

Answer:

Step-by-step explanation:

Here a=1, b=−5i (complex number) and c=−6

α= 2a−b+ b 2 −4ac

and β= 2a−b− b 2 −4ac

α= 2×1(−(−5i)+ (−5i) 2 −4×1×(−6))

=(5i+i)/2

=3i

β= 2×1−(−5i)− (−5i) 2 −4×1×(−6)

=(5i−i)/2

=2i

So, the roots of the given equation are 3i and 2i.
