Question

x-1/x=10 Find x²+1/ײ​

Answer 1

Step-by-step explanation:

$x-\frac{1}{x} = 10$

squaring both sides.

⇒$(x-\frac{1}{x})^{2} = (10)^{2}$

⇒$(x)^{2}+(\frac{1}{x})^{2}+2×x×\frac{1}{x} = 100$

⇒$x^{2}+\frac{1}{x^{2}}+2 = 100$

⇒$x^{2}+\frac{1}{x^{2}} = 100-2$

⇒$x^{2}+\frac{1}{x^{2}} = 98$

Answer 2

Answer:

hope it helps you

Step-by-step explanation:

98

You have to square on both the sides and the expand the variable term on left x and 1/x will get cancelled and 100 - 2 will give 98..
