z= r(cosθ+i sinθ) is the required polar form where, r = √41 and θ =π- 
Step-by-step explanation:
Given,
-4+5i is a complex number.
To find the polar form.
Formula
z=x+iy
r² = mod of (x²+y²)
θ = 
So, the polar form will be z=r(cosθ+i sinθ)
Now,
r² =(-4)²+5² = 41
or, r = √41
θ =π-
[ since the point is in second quadrant]
Hence,
z= r(cosθ+i sinθ) is the required polar form where, r = √41 and θ =π- 
Answer: x=4.5

Answer:
g = x 2 + 2 / x − 3
Step-by-step explanation:
Let's solve for g.
g(x−3)=x2+2
Step 1: Factor out variable g.
g(x−3)=x2+2
Step 2: Divide both sides by x-3.
g(x−3)
x−3
=
x2+2
x−3
g=
x2+2
x−3
