Answer:
a
Step-by-step explanation:
You can use an app called photomath to solve it
Given the coordinates of the vertices of a polygon (−2, −2) , (−2, 3) , (2, 4) , (3, 1) , and (0,−2), the perimeter of the polygon is 18. It is the sum of the length of five sides.
The solution of
are 1 + 2i and 1 – 2i
<u>Solution:</u>
Given, equation is 
We have to find the roots of the given quadratic equation
Now, let us use the quadratic formula
--- (1)
<em><u>Let us determine the nature of roots:</u></em>
Here in
a = 1 ; b = -2 ; c = 5

Since
, the roots obtained will be complex conjugates.
Now plug in values in eqn 1, we get,

On solving we get,



we know that square root of -1 is "i" which is a complex number

Hence, the roots of the given quadratic equation are 1 + 2i and 1 – 2i
