Answer 1

Answer:

question 24

Step-by-step explanation:

(1) (2x-y)^2 = (2x)^2-2×2x×y+(y)^2

= 4x^2-4xy+y^2

(2). (4x+3y)^2 = (4x)^2 + 2×4x×3y + (3y)^2

=. 16x^2+24xy+9y^2

Answer 2

Answer:

24 th question

Step-by-step explanation:

(i) (2x-y)^2

sol:- By using identity (a-b)^2= a^2 - 2ab + b^2

= (2x)^2 -2xy+ y^2

= 4x^2 - 2xy + y^2
