Question

a²-2ab+b²/a²-1 x a-1/ a-b​

Answer 1

Answer:

$\frac{ {a - b} }{a + 1}$

Step-by-step explanation:

using formula!!

» (a - b)² = a² - 2ab + b²

» a² - b² = (a - b)(a + b)

putting formulas!!

$\frac{ {(a - b)}^{2} }{(a - 1)(a + 1)} \times \frac{a - 1}{a - b}$

doing cross multiplication in which we get,

$\frac{ {(a - b)} }{(a + 1)} \times 1$

$\frac{{a - b} }{a + 1}$
