$(2 {x}^{2} - x - 1) \div (x - 1)$
​

Answer 1

GIVEN=>

$(2 {x}^{2} - x - 1) \div (x - 1)$

-------------------

to FIND=

$(2 {x}^{2} - x - 1) \div (x - 1)$=?

-------------------

solution=>

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

----------------------

answer

$= 2x + 1$
