Answer:
Simplification of algebric expression is ![\frac{x^{2} - 2x^{3}-4 }{x^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B2%7D%20-%202x%5E%7B3%7D-4%20%7D%7Bx%5E%7B2%7D%20%7D)
Step-by-step explanation:
Simplify any algebric expression means to write an equivalent expression in which all similar terms combined and remove all symbols such as brackets.
The given algebraic equation is ![x^{2} -\frac{4}{x^{2} } +2x](https://tex.z-dn.net/?f=x%5E%7B2%7D%20-%5Cfrac%7B4%7D%7Bx%5E%7B2%7D%20%7D%20%2B2x)
now for simplifying it
First of all take L.C.M of ![x^{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D)
= ![\frac{x^{2} (x^{2}) -4 + 2x(x^{2} )}{x^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B2%7D%20%28x%5E%7B2%7D%29%20-4%20%2B%202x%28x%5E%7B2%7D%20%29%7D%7Bx%5E%7B2%7D%20%7D)
We get ![\frac{x^{2} -4+2x^{3}}{x^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B2%7D%20-4%2B2x%5E%7B3%7D%7D%7Bx%5E%7B2%7D%20%7D)
Further we can write it as ![\frac{x^{2} - 2x^{3}-4 }{x^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B2%7D%20-%202x%5E%7B3%7D-4%20%7D%7Bx%5E%7B2%7D%20%7D)
