We want to divide 12x^3 + 7x^2 + 14x - 7 by 3x - 3
Thus,
Divisor = 3x - 3
Dividend = 12x^3 + 7x^2 + 14x - 7
Quotient = dividend/divisor
Before filling the blanks, we would carry out the long division process as shown below
The quotient is 4x^2 + 19x/3 + 11 remainder 26
Thus, the answers are
Begin the division process by dividing 12x^3 + 7x^2 + 14x - 7 by 3x - 3, which obtains
4x^2 + 19x/3 + 11 remainder 26
