Question

3x^3+2x^2-15x-10??????

Answer 1

3x^3 + 2x^2 - 15x - 10

= X^2 ( 3x + 2 )- 5 ( 3x + 2 )

=( X^2 - 5) ( 3x + 2 )

= ( x^2 - √5^2 ) ( 3x + 2 )

= ( x + √5 ) ( X - √5 ) ( 3x + 2 ) Ans.

Answer 2

$hey$
$here \: is \: your \: answer$
$3 {x}^{3} + 2 {x}^{2} - 15x - 10 \\ \\ {x}^{2} (3x + 2) - 5(3x + 2) \\ \\ ( {x}^{2} - 5)(3x + 2) \\ \\ \\ \\ hope \: it \: helps$
