Concept

HCF is the largest positive integer that can divides each of the integers. Full form of HCF is highest common factor.

Given

Polynomials f(x)=(x+3)(2x^{2} -3x+a) and g(x)=(x-2)(3x^{2} +10x-b) and HCF of both the polynomials  is (x+3)(x-2)

To find

The values of a and b.

Explanation

We know that HCF divides both the numbers fully means the value of remainder must be 0.

HCF=(x+3)(x-2)

f(x)/HCF=(2x^{2} -3x+a)/(x-2)

Dividing  we get :

2x^{2} -3x+a=(x-2)*(2x+1)(a+2)

means a+2 is remainder so when we put a+2=0, we will get a=-2

g(x)/HCF=(3x^{2} +10x-b)/(x+3)

Dividing we get:

3x^{2} +10x-b=(x+3)*(3x+1)+(-b-3)

means (-b-3) is the remainder so when we put -b-3=0, we will get b=-3.

Hence the value of a=-2 and b=-3 if HCF of f(x)=(x+3)((2x^{2} -3x+a) and g(x)=(x-2)((3x^{2} +10x-b) is (x+3)(x-2).
