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.
= 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.
Thx

Can you give ans in remainder theorem? I can’t solve it
X = -√5 , X = √5 ..?~
X = -√5 , X = √5 ..??
