​

Answer 1

Answer:

YOU SHOULD NOT CHEAT THEREFORE I GAVE EXAMPLE HOW TO DO

Step-by-step explanation:

. Find the H.C.F. x2 – 5x + 4, x2 – 2x + 1 and x2 – 1.

Solution:

Factorizing the quadratic trinomial x2 – 5x + 4, we get

(x)2 – x – 4x + 4

= x(x - 1) – 4(x – 1)

= (x - 4) (x - 1)

Factorizing x2 – 2x + 1 by using the identities (a - b)2, we get

(x)2 – 2 (x) (1) + (1)2

= (x – 1)2

Factorizing x2 – 1 by using the differences of two squares, we get

= x2 – 12

= (x + 1) (x – 1)

Therefore, H.C.F. of x2 – 5x + 4, x2 – 2x + 1 and x2 – 1 is (x – 1
