Question

Expand : (x² - 1/x)²​

Answer 1

Answer:

x^6−2x^3+1/x2

Step-by-step explanation:

(x^2−1/x)^2=x^6−2x^3+1/x2

Answer 2

Answer :

= ${\sf{({{x}^{2} - \dfrac{1}{x}}^{2})}}$

= ${\sf{({ \dfrac{{x}^{3}-1}{x}}^{2})}}$

= ${\sf{ \dfrac{{({x}^{3}-1}^2)}{{x}^{2}}}}$

= ${\sf{\dfrac{{({x}^{6}-2{x}^{3} + 1}^2)}{{x}^{2}}}}$

That's the answer !!
