Question

4) Divide. ( 2x 2 –x–1) ÷ (x–1) and please answer only if you don't know please don't answer ​

Answer 1

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

HOPE IT HELPS YOU...

Answer 2

Answer:

solution=>

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

answer=>

remider

$= 2x + 1$
