Question

x2+x-56 by factorisation
​

Answer 1

Answer:

56-2=54

then, 54×2=108

Answer 2

$\blue\implies {x}^{2} + x - 56 \\ \\\purple\implies {x}^{2} + (8 - 7)x - 56 \\ \\ \red\implies {x}^{2} + 8x - 7x - 56 \\ \\\pink\implies x(x + 8) - 7(x + 8) \\ \\\green\implies \bf(x + 8)(x - 7) \\ \\ \tt\: this \: is \: required \: factoristion \:$
