Write the conjugate of the following complex
number:
-6i

Step-by-step explanation:

We want to write the conjugate of the complex number:

Recall that the conjugate of a complex number in the form a + bi is a - bi, and vice versa.

We can rewrite our complex number as:

Hence, a = 0 and b = 6.

Then its conjugate will be:

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
