Answer 1

Answer:

49x²/4

Step-by-step explanation:

By (a-b)²=(a²+b²-2ab)

(4x-1/2x)²={(4x)²+(1/2x)²-(2×4x×1/2x)

=16x²+1/4x²-4x²

=49x²/4

I hope this answer will help you!

Answer 2

Step-by-step explanation:

(4x-1/2x)²

by using identity

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

(4x-1/2x)² = (4x)^2+(1/2x)^2 -2 x (4x) x 1/2x

= 16x^2+1/4x^2 - 4
