Solution
The correct option is C -2 and 6
x2−2x−3)x3−2x2+ax−b(x x3−2x2−3x(a+3)x−b
Remainder =(a+3)x-b=x-6 (given)
equality coeffication of x & constant
a+3=1 & b=6
a=-2 & b=6
x2−2x−3)x3−2x2+ax−b(x x3−2x2−3x(a+3)x−b
Remainder =(a+3)x-b=x-6 (given)
equality coeffication of x & constant
a+3=1 & b=6
a=-2 & b=6
