Question

factorise the following =x^2-36​

Answer 1

Answer:

$x {}^{2} - 36 = 0$

$x {}^{2} = 36$

$x = \sqrt{36}$

$x = 6$

this is the answer

Answer 2

Step-by-step explanation:

$x {}^{2} - 36 \\ = {x}^{2} - {6}^{2} \\ = (x - 6)(x + 6)$

Use this identity

${x}^{2} - {y}^{2} = (x - y)(x + y)$
