Question

Find HCF of (x+1)(x²-4) and(x²-1)(x-2) is

Answer 1

Answer:

(x+1)

Step-by-step explanation:

(x+1)(x.x-4) here x.x -4 or x.x -2.2 is in the form of a.a-b.b

=(x+1)(x+2)(x-2)

(x.x-1)(x-2)

=(x.x-1.1)(x-2) here x.x-1.1 is also is in the firm of a.a-b.b

=(x+1)(x-1)(x-2)

So,here the common factors are (x+1)&(x-2)

So, the hcf is (x+1).
