Answer 1

Answer:

Here x-1 and x+2 are the factors.

From these u can find the value of x. (it would be 1 and - 2).

Now, put x=1 in eq. And solve it.

Then, put x=-2 in eq. And solve it

After solving u will get 2 different eq.

Then find the value of a and b after solving both the equations by subsitution method.

Then u can easily calculate the value of a+b.

Hope it helps..

Answer 2

Answer:

(-47) is the value of a+b
