Question

find product of (5a - 3b) (25a square + 15ab + 9b square)

Answer 1

HELLO.........FRIEND!!

THE ANSWER IS HERE,

$= > \: (5a - 3b)(25 {a}^{2} + 15ab + 9 {b}^{2} )$

This is in the form of ,

$= > \: (x - y)( {x}^{2} + xy + {y}^{2} )$

So,

$= > \: (x - y)( {x}^{2} + xy + {y}^{2} ) = {x}^{3} - {y}^{3}$

Here, x=5a ; y =3b.

$= > \: {x}^{3} - {y}^{3} = ({5a})^{3} - ({3b)}^{3}$

$= > \: 125 {a}^{3} - 27 {b}^{3}$


:-)Hope it helps u.
