Find the quotient of these complex numbers. (4+4i)+(5+4i)

Step-by-step explanation:

We are asked to find the quotient so I am assuming the question should have been: .

When we are to find we will multiply the numerator and denominator by the conjugate of the denominator. i.e., .

Therefore,

.

Multiplying the numerator, we have: .

Therefore the answer is: .

Hence, the answer.

e.

step-by-step explanation:

because there are always 10 numbers in a phone number.

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
