Question

H.C.F of 4a2-b2 and b2-2ab
​

Answer 1

Answer:

( 2a - b)

Step-by-step explanation:

formula --->

_____________

p^2 - q^2= (p + q) (p - q)

4a^2 -b^2=(2a) ^2- ( b) ^2

= (2a+b) (2a-b)

b^2-2ab= b ( b - 2a)

=-b (2a - b)

H. C. F= (2a - b)

Answer 2

(4a^2 - b^2)

=>((2a)^2 - (b)^2) [ by using a^2 - b^2 = (a-b)(a+b)]

=>(2a - b)(2a + b)

(b^2-2ab)

=(-b(b-2a))

2a-b is ans
