Question
Factorise $:2\sqrt3x^2 + x - 5\sqrt3$
✓
Answer
$2\sqrt3x^2 + x - 5\sqrt3$
$= 2\sqrt3x^2+ 6x - 5x - 5\sqrt3$
$= 2\sqrt3x( x + \sqrt3 ) - 5( x + \sqrt3 )$
$= ( 2\sqrt3x - 5 )( x + \sqrt3 )$
$= 2\sqrt3x^2+ 6x - 5x - 5\sqrt3$
$= 2\sqrt3x( x + \sqrt3 ) - 5( x + \sqrt3 )$
$= ( 2\sqrt3x - 5 )( x + \sqrt3 )$
