Question

coefficient of x^2 (x/2 - y/2)^2

Answer 1

Answer:

2 is the coefficient of x²

hope this helps

Answer 2

Answer: (x/2 - y/2)^2

=$(\frac{x}{2} ) ^{2} +(\frac{y}{2} )^{2} +2(\frac{x}{2})(\frac{y}{2})$

=$\frac{x^{2} }{4} +\frac{y}{4} ^{2} +\frac{xy}{2}$

coefficient of $x^{2}$ is  $\frac{1}{4}$.
