x^2 + 2x + 5 = 0.Find the root of this eqn.can use polar system.
is the answer=(-1+2i) @ (-1-2i)??
pls help...
thanx...

A polar coordinate equation is a mathematical representation of a point in a two-dimensional coordinate system using a distance from the origin and an angle from a fixed reference axis.
To convert a polar coordinate equation to rectangular form, you can use the following formulas:
x = r cos(theta)
y = r sin(theta), where r is the distance from the origin and theta is the angle from the reference axis.
Yes, a polar coordinate equation can have multiple solutions. This is because a single point in a polar coordinate system can have multiple representations in a rectangular coordinate system.
To find the roots of a polar coordinate equation, you can convert it to rectangular form and then use the quadratic formula. In this case, the roots would be in the form of (x,0) as y is always equal to 0 in a polar coordinate system.
Yes, a polar coordinate equation can have complex roots. This occurs when the quadratic formula results in a negative discriminant. In this case, the roots would be in the form of (x,0) + (0,y) or (x,0) - (0,y) where y is a non-zero imaginary number.
