Question
Factorise $: 24a^3+ 37a^2- 5a$
✓
Answer
$24a^3+ 37a^2 - 5a$
$= a( 24a^2 + 37a - 5 )$
$= a( 24a^2 + 40a -3a - 5 )$
$= a \times [ 8a( 3a + 5 ) - 1( 3a + 5 )]$
$= a[( 8a - 1 )( 3a + 5 )]$
$= a( 8a - 1 )( 3a + 5 )$
$= a( 24a^2 + 37a - 5 )$
$= a( 24a^2 + 40a -3a - 5 )$
$= a \times [ 8a( 3a + 5 ) - 1( 3a + 5 )]$
$= a[( 8a - 1 )( 3a + 5 )]$
$= a( 8a - 1 )( 3a + 5 )$
