find the continued product (3a - 5b)(3a + 5b)(9a² + 25b²)
Given (3a - 5b)(3a + 5b)(9a² + 25b²)
= (3a - 5b) [(3a)² + (3a) (5b) + (5b)²
= (3a)³ - (5b)³
/ By algebraic identify /
( x - y ) ( x² + xy + y² ) = x³ - y³
= 27a³ - 125b³
Therefore.,
( 3a - 5b ) ( 9a² + 15ab + 25b² )
= 27a³ - 125b³
HOPE IT'S HELPFUL
