தொகு‌முறை வகு‌த்த‌ல்:

(i) x^3 - 3x^2 - 10x + 24

தீர்வு:

p(x) = 2;

p(2) = 2^3 - 3(2)^2 - 10(2) + 24 = 0

Refer diagram  (1)

x^2 - x -12 = 0

x^3 - 3x^2 - 10x + 24

= (x + 3) (x - 4) (x - 2)

(ii) 2x^3 - 3x^2 - 3x + 2

தீர்வு:  

p(-1) = 2 (-1)^2 - 3(-1)^2 -3 (-1) + 2 = 0

Refer diagram (2).

2x^3 -5x - 2 = 0

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

= (x - \frac{1}{2}) (x - 2) (x + 1)

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