Question

find HCF of a and b is equal to 3 x square Y and B equal to 6 x y cube

Answer 1

Factorizing 4x2 - 9y2, we get

(2x)2 - (3y)2, by using the identities of a2 - b2. 

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



 


Also, factorizing 2x2 – 3xy by taking the common factor 'x', we get 

= x(2x – 3y)

Therefore, H.C.F. of the polynomial 4x2 - 9y2 and 2x2– 3xy is (2x - 3y).

Answer 2

Ans: H.C.F( 3x^2y , 6xy^3)

a = 3 × x × x × y
b = 2 × 3 × x × y × y × y

H.C.F = 3xy
