Question

(x+1) (x+1) / x- 1= x+1

Answer 1

Answer:

x = - 1

Step-by-step explanation:

$\frac{(x+1)(x+1)}{x-1}$ = x + 1 ⇔ (x + 1)² = (x - 1)(x + 1) ⇔ (x + 1)² = x² - 1

x² + 2x + 1 = x² - 1 ⇔ 2x + 1 = - 1 ⇒ x = - 1

Answer 2

Step-by-step explanation:

(x+1) (x+1)/x-1=x+1

(x+1) (x+1)/x-1=x+1/1

x2+x+1/x-1=x+1/1

x2+x+1=(x+1) (x+1)

x2+x+1=x2+x-1

x=2
