–3

Here x is common factor in x^3 + x and – 3 is common factor in –3x^2 – 33x

–3

x^3 – 3x^2 + x – 3x

3

–3x

2

+x–3

x^2 (x – 3) + 1(x – 3)x

2

(x–3)+1(x–3)

Taking ( x – 3) common

(x – 3) (x^2 + 1)(x–3)(x

2

+1)

Therefore x^3 + x – 3x^2 – 3 = (x – 3) (x^2 + 1)x

3

+x–3x

2

–3=(x–3)(x

2

+1)

2x+3=0

2x= -3

x=-3/2
