Factorize $2x^4 - 3x^3 - 3x - 2$ :

a $(x-2)(2x+1)(x^2 + 1)$
b $(x+2)(2x-1)(x^2 + 1)$
c $(x-2)(2x-1)(x^2 + 1)$
d $(x+2)(2x+1)(x^2 + 1)$

ব্যাখ্যা

Both $x=2$ and $x=-\tfrac12$ make the expression zero, giving factors $(x-2)$ and $(2x+1)$ . The remaining quotient is $x^2 + 1$ , which has no real roots.
