The trigonometric form of the complex number 1 + 3i is 3.16[cos(71.57)° + isin(71.57°)]
<h3>What is an equation?</h3>An equation is an expression that shows the relationship between two or more numbers and variables.
Complex number is in the form z = a + bi, where a, b are real numbers.
Given the complex number z = 1 + 3i
In polar form: r = √(1² + 3²) = 3.16
Ф = tan⁻¹ (3/1) = 71.57⁰

We have been given a Quadratic equation, where we have to find the real values of x ~
So, let's proceed with middle term splitting method :
Now, we have two conditions here~
Either (x + 6) = 0
or (x - 1) = 0
