Answer:

<2 = 129°

Step-by-step explanation:

if I || m then 5x+12 =m<2 and m<2 + 2x + 14 = 180°

2x + 14 + 5x + 12 = 7x + 26 =180°

7x = 154 ➡x = 21°

m <2 = 5×21 + 14

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).
