Question
We are given the following homogenous differential equation and pair of solutions on the given interval.
x²y" - 4xy' + 6y = 0; x², x³, (0, ∞)
We are asked to verify that the solutions are linearly independent. That is, there do not exist constants c₁ and C₂, not both zero, such that c₁x² + ₂x³ = 0. While this may be clear for these solutions that are different powers of x, we have a formal test to verify
the linear independence.
Recall the definition of the Wronskian for the case of two functions f₁ and f2, each of which have a first derivative.

W(f₁, f₂) =
f₁' f₂
By Theorem 4.1.3, if W(f₁, f₂) = 0 for every x in the interval of the solution, then solutions are linearly independent.
Let f₁(x) = x² and f₂(x) = x³. Complete the Wronskian for these functions.
