How to solve in division of polynomials

Sagot :

ex. of 2x²+9x-12/2x+3
first is 2x² divide 2x=x,x(2x)=2x²,x(3)=3x
        2x²+9x-12 second is 6x divide 2x=3, 3(2x)=6x, 3(3)=9
(+)- -2x²-3x
             6x-12
       (+)-6x-9
                -21                  -21       
and the answer is x+3+  2x²+9x-12
