Question

factorise x^2 - 5√2 x -12

Answer 1

Hey

Here is your answer,

X^2 - 5√2 x - 12 = 0
X^2 + √2x - 6√2x - 12 = 0
X ( x + √2 ) - 6√2 ( x + √2) = 0
( X + √2) ( x - 6√2) = 0
X+√2 = 0
X = -√2
X - 6√2 = 0
X = 6√2

Hope it helps you!

Answer 2

Heya !!



X² - 5√2X - 12




X² - 6√2X + √2X - 12


X ( X - 6√2 ) + √2 ( X - 6√2 )




( X - 6√2 ) ( X + √2 ).
