Perform the indicated operation and write the result in the form a+bi. 2(i-14)-i(i+1)

a.-13+i

b.-27+i

c.-29+3i-29+i

d.-29+i

Please select the best answer from the choices provided A B C D

b)  - 2 7 + i

Step-by-step explanation:

Explanation:-

Given    2 ( i -14) -i ( i+1)

          =   2 i - 28 - i² - i

          =   2 i - 28 - (-1) - i

          =   2 i - 28 + 1 - i

           =  - 2 7 + i

step-by-step explanation:

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
