Answer 1

Answer:

3) (x+1),(x+2) and (x-2) are factors of given polynomial.

4) (3x - 1) (x+1) (x-1)

Step-by-step explanation:

3)

Given x³+x²-4x-4

= x²(x+1)-4(x+1)

= (x+1)(x²-4)

= (x+1)(x²-2²)

= (x+1)(x+2)(x-2)

So , By algebraic identity:

a²-b² = (a+b)(a-b) */

Therefore,

(x+1),(x+2) and (x-2) are factors of given polynomial.

4)

3x^3 - x^2 - 3x + 1

= x^2 ( 3x - 1 ) - 1 ( 3x - 1 )

= ( 3x - 1 ) ( x^2 - 1 )

Therefore,

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