Question

दिलेल्या समीकरणांपैकी वर्गसमीकरणे कोणती ते ठरवा: $\rm x+\frac{1}{x}=-2$

Answer 1

Answer:

Step-by-step explanation:

x + 1 /x = - 2

x^2 + 1 = - 2x

x^2 + 2x + 1 = 0

(x + 1)^2 = 0

x = - 1.

Answer 2

Answer:

x = -1 or x = -1

Explanation :

x +1/x = -2

=> (x²+1)/x = -2

=> x²+1 = -2x

=> x²+2x+1 = 0

=> x² + 2*x*1+1² = 0

=> (x+1)²=0

=> x +1=0 or x+1=0

=> x = -1 or x = -1
