Polynomial Division (Edexcel A-Level Mathematics): Quizzes

$x^3 + 2x^2 + 5$

$3$

Divide $x^2$ by $x$

$x + 2 + \frac{3}{x+1}$

$-19$

Substitute $x=-2$ into $f(x)$

Show $f(3) = 0$

$x^2 - 6x - 11 = 0$

$x = 3 \pm 2\sqrt{5}$

Year 2 allows non-linear divisors

$x^3-2x^2+7x-5-\frac{2}{x+2}$

$23x$
