Question

Please help me friends. ​

Answer 1

Answer:

I am very weak in maths sorry

Answer 2

With (a+b)² = a² + b² + 2ab

x = a ; y/2 = b

${(x + \frac{y}{2}) }^{2} \\ \\ = {x}^{2} + {\frac{y}{4} }^{2} + 2 \times x \times \frac{y}{2} \\ \\ = \boxed{{x}^{2} + { \frac{y}{2} }^{2} + xy}$

I HOPE IT HELPED YOU.
