degrees zero means its a normal number as x^0=1
hence divide (2x^3 + 5x^2-14x +10) by (2x-3)
remainder is 7
hence 7 should be added so that 2x^3 +5x^2 -14x +10 is exactly divisible by 2x-3
therefore g(x) is 7
The expression that should be subtracted from the polynomial f(x) = x4 + 2x3 -13x2 - 12x + 21 so that the resulting polynomial is exactly divisible by g(x) = x2 – 4x + 3 is
