Question

Factorise the following
$2x {}^{2} - 24x + 72$
​

Answer 1

Answer:

$2(x - 6)(x - 6)$

Step-by-step explanation:

$2 {x}^{2} - 24x + 72 \\ \\ = 2 ({x}^{2} - 12x + 36)$

$= 2 ({x - 6}) ^{2} \\ \\ = 2(x - 6)(x - 6)$

Hope it helps

Answer 2

Step-by-step explanation:

$= 2 {x}^{2} −24x+72 \\ = 2( {x}^{2} - 12x + 36)\\ = 2( {x}^{2} - 6x - 6x + 36) \\ = 2(x(x - 6) - 6(x - 6)) \\ = 2(x - 6)(x - 6) \\ = 2 {(x - 6)}^{2}$
