Question

[5x-3y) (25x² + 15 xy + 9y^2] solve using suitable identity ​

Answer 1

Answer:

$(5x - 3y)( 25 {x}^{2} + 15xy + 9 {y}^{2} \\ \\ 125 {x}^{3} + 75 {x}^{2} y + 45x {y}^{2} - 75 {x}^{2} y - 45x {y}^{2} - 27 {y}^{3} \\ \\ 125 {x}^{3} + 27 {y}^{3} \\ \\( 5x)^{3} +( 3y) ^{3} \\ \\ \\( 5x + 3y)(25 {x}^{2} - 15xy + 9 {y}^{2} )$
