Question

Factorise by splitting the middle term x²-9x-22​

Answer 1

Step-by-step explanation:

${x}^{2} - 9x - 22 = 0$

${x}^{2} - 2x + 11x - 22 = 0$

$x(x - 2) + 11(x - 2) = 0$

$(x + 11)(x - 2) = 0$

$x = - 11 \: \: \: or \: \: \: 2$

Answer 2

Answer:

${x}^{2} - 9x - 22$

${x}^{2} - 11x + 2x - 22$

$x(x - 11) + 2(x - 11)$

$(x - 11)(x + 2)$
