Question

If (x-b) is the HCF of f(x) = x^2 + ax + 1 and g(x) = x^2 - 3x + 2, find the value of a and b.

Answer 1

Answer:

The value of a is  -2 and b is 1.

here, g (x) = x^2 - 3x + 2 ==>

(x-2) & (x-1) this shows that the value of "b" will be  2 or 1.

So that it is fine to check that options which, b is 2 or b is 1.
