Question

guys plz give answer with proper information ​

Answer 1

Step-by-step explanation:

We have,

${x}^{3} + 7 {x}^{2} + 7x - 15$

$= {x}^{3} - {x}^{2} + 8 {x}^{2} - 8x + 15x- 15$

$= {x}^{2}(x - 1)+ 8x (x - 1) + 15(x- 1)$

$= (x - 1)({x}^{2}+ 8x + 15)$

$= (x - 1)({x}^{2}+ 5x + 3x + 15)$

$= (x - 1) \{x(x+ 5) + 3(x + 5) \}$

$= (x - 1) (x+ 5) (x + 3)$
