Question

X square - 7 x -18 by x- 9

Answer 1

$\bf \frac{ {x}^{2} - 7x - 18 }{x - 9} \\ \\ \bf = > \frac{ {x}^{2} - 9x + 2x - 18 }{x - 9} \\ \\ \bf = > \frac{x(x - 9) + 2(x - 9)}{x - 9} \\ \\ \bf = > \frac{(x + 2)(x - 9)}{x - 9} = x + 2$

• Hence, When (x² - 7x - 18) is divided by (x - 9) , the remainder would be (x + 2) .
