Answer:
x = a/(a² + b²) or x = -1/a
Step-by-step explanation:
a(a²+ b²)x² + b²x - a =0
Use the quadratic equation formula:
![x = \dfrac{-b\pm\sqrt{b^2-4ac}}{2a} =\dfrac{-b\pm\sqrt{D}}{2a}](https://tex.z-dn.net/?f=x%20%3D%20%5Cdfrac%7B-b%5Cpm%5Csqrt%7Bb%5E2-4ac%7D%7D%7B2a%7D%20%3D%5Cdfrac%7B-b%5Cpm%5Csqrt%7BD%7D%7D%7B2a%7D)
1. Evaluate the discriminant D
D = b² - 4ac = b⁴ - 4a(a² + b²)(-a) = b⁴ + 4a⁴ + 4a²b² = (b² + 2a²)²
2. Solve for x
![\begin{array}{rcl}x & = & \dfrac{-b\pm\sqrt{D}}{2a}\\\\ & = & \dfrac{-b^{2}\pm\sqrt{(b^{2}+2a^{2})^{2}}}{2a(a^{2} + b^{2})}\\\\ & = & \dfrac{-b^{2}\pm(b^{2}+ 2a^{2})}{2a(a^{2} + b^{2})}\\\\x = \dfrac{-b^{2}+(b^{2} + 2a^{2})}{2a(a^{2} + b^{2})}&\qquad& x =\dfrac{-b^{2}-(b^{2} + 2a^{2})}{2a(a^{2} + b^{2})}\\\\x =\dfrac{-b^{2}+(b^{2} + 2a^{2})}{2a(a^{2} + b^{2})}&\qquad& x =\dfrac{-b^{2}-(b^{2} +2a^{2})}{2a(a^{2} + b^{2})}\\\\\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Brcl%7Dx%20%26%20%3D%20%26%20%5Cdfrac%7B-b%5Cpm%5Csqrt%7BD%7D%7D%7B2a%7D%5C%5C%5C%5C%20%26%20%3D%20%26%20%5Cdfrac%7B-b%5E%7B2%7D%5Cpm%5Csqrt%7B%28b%5E%7B2%7D%2B2a%5E%7B2%7D%29%5E%7B2%7D%7D%7D%7B2a%28a%5E%7B2%7D%20%2B%20b%5E%7B2%7D%29%7D%5C%5C%5C%5C%20%26%20%3D%20%26%20%5Cdfrac%7B-b%5E%7B2%7D%5Cpm%28b%5E%7B2%7D%2B%202a%5E%7B2%7D%29%7D%7B2a%28a%5E%7B2%7D%20%2B%20b%5E%7B2%7D%29%7D%5C%5C%5C%5Cx%20%3D%20%5Cdfrac%7B-b%5E%7B2%7D%2B%28b%5E%7B2%7D%20%2B%202a%5E%7B2%7D%29%7D%7B2a%28a%5E%7B2%7D%20%2B%20b%5E%7B2%7D%29%7D%26%5Cqquad%26%20x%20%3D%5Cdfrac%7B-b%5E%7B2%7D-%28b%5E%7B2%7D%20%2B%202a%5E%7B2%7D%29%7D%7B2a%28a%5E%7B2%7D%20%2B%20b%5E%7B2%7D%29%7D%5C%5C%5C%5Cx%20%3D%5Cdfrac%7B-b%5E%7B2%7D%2B%28b%5E%7B2%7D%20%2B%202a%5E%7B2%7D%29%7D%7B2a%28a%5E%7B2%7D%20%2B%20b%5E%7B2%7D%29%7D%26%5Cqquad%26%20x%20%3D%5Cdfrac%7B-b%5E%7B2%7D-%28b%5E%7B2%7D%20%2B2a%5E%7B2%7D%29%7D%7B2a%28a%5E%7B2%7D%20%2B%20b%5E%7B2%7D%29%7D%5C%5C%5C%5C%5Cend%7Barray%7D)

Outsourcing is well known as just an exercise which takes occurs when a company, therefore the answer is "Option b" that is "Outsourcing", and the further discussion can be defined as follows:
- It gives another business a task to perform or to undertake for them rather than themselves.
- It is an agreement between the two companies, usually for a specified period.
- It is made to be better efficient and to minimize the costs.
- In the large marketing company agreements for worker cheques with such a payroll service provider, they outsource people.
Therefore, the final answer is "Option b".
