solve the following equation by factorisation 1. x²+2x=24

➟$\bf{\underline{\underline{Solution}}}$

$\bf{x^{2}\:+2x\:=\:24}$

$\bf{x^{2}\:+2x\: -\:24\:=\:0}$

$\bf{x^{2}\:+6x\: -4x\: -\:24\:=\:0}$

$\bf{x(x+6)\: -4(x+6)\:=\:0}$

$\bf{(x+6)\: (x-4)\:=\:0}$

1.$\bf{(x+6)\:=\:0\:=>\:-6}$

2.$\bf{(x-4)\:=\:0\:=>\:4}$
