Pani-rosa [81]
Answer: They would make $28.76.

Explanation: If 7 video games are worth $100.66, when you divide 100.66 by 7(100.66/7) you get the amount of money that 1 video game would be worth which is $14.38. Multiply 14.38 by 2(the number of video games they sold) and you get the answer of 28.76(the total money they made).

What is the complete factorization of the polynomial function over the set of complex numbers? f(x)=x^3+3x^2+16x+48
Tamiku [17]

Answer:(x+3)(x+4i)(x-4i)  is the required factorization of f(x).


Step-by-step explanation:

To factor the expression we must first group the terms and then take out common from these groups

f(x)=x^3+3x^2+16x+48=(x^3+3x^2)+(16x+48)

Taking x^2 common from first group and the 16 from second group we get:


f(x) = x^2(x+3)+16(x+3) = (x+3)(x^2+16)


Now, to factor in complex from we have to break term x^2+16


f(x)= (x+3){x^2-(-4i)^2}

As, i^2 = -1 , therefore (-4i)^2 = 16i^2 =-16

Also using identity a^2-b^2 =(a+b)(a-b)

On solving

f(x) = (x+3)(x+4i)(x-4i)

(x+3)(x+4i)(x-4i)  is the required factorization of f(x).
