Answer:

Step-by-step explanation:

f(x) = x^2 + 5

g(x^2 + 5) = (x^2 + 5)^2= x^4 + 5x^2 + 5x^2 + 25 = x^4 + 10x^2 + 25

h(x^4 + 10x^2 + 25)= -2(x^4 + 10x^2 + 25)

-2x^4 - 20x^2 - 50

What is the quotient of the complex number 4-3i divided by its conjugate ?

mina [271]

Answer:

Quotient is $\frac{7-24i}{25}$

Step-by-step explanation:

Given is a complex number as 4-3i

We have to find the quotient when divided by its conjugate

Its conjugate is

$4+3i$

When divided we have

$\frac{4-3i}{4+3i} =\frac{4-3i}{4+3i} \frac{4-3i}{4-3i}$

(to simplify the above)

= $\frac{(4-3i)^2}{4^2+3^2} \\=\frac{7-24i}{25}$

Quotient is $\frac{7-24i}{25}$
