Question

Factorise х^2+√2x - 4 = 0​

Answer 1

Step-by-step explanation:

$x ^{2} + \sqrt{2} x - 4 = 0 \\ \\ {x }^{2} + 2\sqrt{2} x - \sqrt{2} x - 4 = 0 \\ \\ x(x + 2 \sqrt{2} ) - \sqrt{2} (x + 2 \sqrt{2} ) = 0 \\ \\ (x - \sqrt{2} )(x + 2 \sqrt{2} ) = 0 \\ \\ x = \sqrt{2} \\ \\ x = - 2 \sqrt{2}$

Answer 2

here is your answer

$2 \sqrt{2}$
