Question

The factorisation of $a(x + y + z) + b(x + y + z) + c(x + y + z)$

Answer 1

$\boxed{\sf{\bigstar\:\:\mathrm{Factor}\:a\left(x+y+z\right)+b\left(x+y+z\right)+c\left(x+y+z\right)}}$

$a\left(x+y+z\right)+b\left(x+y+z\right)+c\left(x+y+z\right)$

$\mathrm{Factor\:out\:common\:term\:}\left(x+y+z\right)$

$\sf{\large\boxed{=\left(x+y+z\right)\left(a+b+c\right)}}}$
