தொகு‌முறை வகு‌த்த‌ல்:

(i)4x^3 - 7 x + 3  

தீர்வு:  

= 4x^3 + 0x^2 -7x + 3

p (x) = 1

p( 1 ) = 4( 1 ) - 7( 1 ) + 3( 1 )

p( 1 ) = 4 - 7 + 3 = 0

Refer the diagram  (1)

4x^2 + 4 - 3

-7 x + 3 + 4x^3

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

(ii) x^3 + x^2 - 14 x - 24

தீர்வு:  

p (x) = 2

p( -2 ) = - 8 + 4 + 28 - 24

= - 32 - 32 = 0

Refer the diagram (2)

(x + 6)  x^2 - x - 12

x^3 + x^2 - 14x - 24

= (x^2 - x - 12) (x + 6)

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