1 answer

To find the quotient of a complex number divided by its conjugate, we need to multiply both the numerator and denominator by the conjugate of the denominator.

The complex number is 4-3i, and its conjugate is 4+3i.

Therefore, the fraction becomes:

(4-3i) / (4+3i)

Multiplying both the numerator and denominator by the conjugate of the denominator:

[(4-3i)(4-3i)] / [(4+3i)(4-3i)]

Expanding both the numerator and denominator:

(16 - 12i - 12i + 9i^2) / (16 - 12i + 12i - 9i^2)

Simplify:

(16 - 24i + 9i^2) / (16 - 9i^2)

Remember that i^2 = -1:

(16 - 24i - 9) / (16 + 9)

Combine like terms:

(7 - 24i) / 25

So, the quotient of the complex number 4-3i divided by its conjugate is:

(7 - 24i) / 25
