Answer:
<h2>
12(cos120°+isin120°)</h2>
Step-by-step explanation:
The rectangular form of a complex number is expressed as z = x+iy
where the modulus |r| = 
and the argument 
In polar form, x = 
Given the complex number, 
. To express in trigonometric form, we need to get the modulus and argument of the complex number.
For the argument;
Since tan is negative in the 2nd and 4th quadrant, in the 2nd quadrant,
z = 12(cos120°+isin120°)
This gives the required expression.
Answer:
(x + 2)(x + 8)
Step-by-step explanation:
x² + 10x + 16
consider the factors of the constant term (16) which sum to give the coefficient of the x- term.
the factors are + 2 and + 8 , since
+ 2 × + 8 = + 16 and + 2 + 8 = + 10 , then
x² + 10x + 16 = (x + 2)(x + 8) ← in factored form
