(2x3 − 3x2 + x − 6) ÷ (x − 4)
other way of solving
it's hard to type the usual one
i forgot what it's called
2 -3 1 -6 4
____8__20__84
2 5 21 78
bring down the first and then times the divisor which is 4 and then add with the next number and so on
the last number will be the remainder
the variable of the first one is the higher exponent minus 1 and so on
the answer is
2x^2 + 5x + 21 r. 78
