When u divide 3x3+x2-22x+9 with 3x2+7x-6 u get the remainder as -14x -3 nd when -14x -3 is added to 3x3+x2-22x +99 it is exactly divisible by 3x2+7x-6

Ok then delete it
but remainder is somthng else
I think I hav done some silly mistake
check it
Division gives the remainder (-2x -3).

Therefore to make the given expression exactly  by 3x² +7x -6,
add [(3x² +7x -6) - (-2x-3), i.e., 3x² + 9x -3 to the expression (3x³ +x² -22x +9)
