Answer 1

Answer:

➡Expansion of

(1/4a-1/2b+1)²

=> 1/16a²+1/4b²+1

=> -1/4ab-1/b+1/2a

Step-by-step explanation:

➡ Expansion of

(1/4a-1/2b+1)²

⭐ We know the algebraic identity:-⭐

(x+y+z)²

= x²+y²+z²+2xy+2yz+2zx

----------------------------------

=> [(1/4a)² + (-1/2b)²+1]²

=> (1/4a)² + (-1/2a)² +1 +2×1/4a×-1/2+-1/2b×1+2×1×1/3a

=> 1/16a² + 1/4b² + 1

-1/4ab - 1/b + 1/2a✔
