Solve an Algebraic Equation

When we code the above program,

If we input x = 0 we can get output as y = - 1.0

If we input x = 1 we can get output as y = 3.0

If we input x = -1 we can get output as y = - 9.0

Let’s consider about another equation.

When we code the above program,

If we input x = 1 we can get output as y = 0.6000000000000001

If we input x = 10 we can get output as y = 0.09901951266867294

If we input x = 100 we can get output as y = 0.009999000199950014

If we input x = -5 we can get output as y = -0.19258202567760344
