Question

factorise
$x2 - x - 110$

Answer 1

Answer :

Now, x² - x - 110

= x² - (11 - 10)x - 110, since 110 = 11 × 10

= x² - 11x + 10x - 110

= x (x - 11) + 10 (x - 11)

= (x - 11) (x + 10),

which is the required factorization.

Answer 2

Find numbers whose sum is -1 and product is -110.
They are -11 & 10.
${x}^{2} - x - 110 = {x}^{2} - 11x + 10x - 110 \\ x(x - 11) + 10(x - 11) \\ (x - 11)(x + 10) \: are \: \: the \: \: factors$
