Question

facterise 250x³-432y³

Answer 1

Hey Karan !


Here is your solution :

= 250x^3 - 432y^3


By taking 2 as common ,


= 2 ( 125 x^3 - 216 y^3 )


= 2 { ( 5x )^3 - ( 6y )^3 }


Using identity :

( a^3 - b^3 ) = ( a - b ) ( a^2 + b^2 + ab )



= 2 ( 5x - 6y ) { ( 5x )^2 + ( 6y )^2+5x × 6y }


= 2 ( 5x - 6y ) ( 25x^2 + 36y^2 + 30xy )



===================================


Hope it helps !!
