if the quotient obtained in dividing x^2 - 7x + b by x + a is x - 2, and the remainder is 5, then what are the values of a and b?
anybody can help on this?

We have . Expanding the LHS and comparing the coefficients on both sides we have
We are told:
Now, equate coefficients to get two equations, from which you may determine a and b.
