If p(x) is divided by 3x + 2 gives the quotient 4x2 - 2x - 1 and remainder 3 , what is p(x)?
12x3 - 2x2 + 7x - 1
12x3 - 2x2 - 7x + 1
12x3 + 2x2 - 7x + 1
12x3 + 2x2 - 7x - 1
(3x3 + 3x2 - 4x + 5 ) + (x3 - 2x2 + x - 4 ) =
4x3 + x2 - 3x + 1
4x3 + 5x2 + 5x + 9
4x3 - x2 + 3x - 1
4x3 - x2 - 3x - 1
2 - 2x - x2 ÷ (1 - x) we get the remainder
