i worte the quauatoin wrong it is :-
(3x-2) (2xsquared + x - 4 )

(3x-2) (2x² + x - 4 )
3x --> 6x^3 + 3x² -12x
-2 --> .......... -4x²..-2x + 8
.......... ===============
.......... 6x^3 - x² - 14x + 8

(3x-2)(2x^2 +x -4)
=6x^3 +3x^2 -12x -4x^2 -2x +8
=6x^3 -x^2 -14x +8

(3x-2) (2x^2-4)
= 6x^3-12x-4x^2+8
= 6x^3-4x^2-12x+8=0

(3x - 2)(2x^2 + x - 4)
Multiply the polynomials
2x^2 + x - 4
. . . . .3x - 2
- - - - - - - - -
6x^3 + 3x^2 - 12x
. . . . .- 4x^2 - 2x + 8
- - - - - - - - - - - - - - -
6x^3 - x^2 - 14x + 8
