Q. The binomial expansion of (x2+y)2 \left(x^{2}+y\right)^{2} is \qquad \newlineA. x2+2x2y+y2 x^{2}+2 x^{2} y+y^{2} \newlineB. x4+2x3y+x2y2 x^{4}+2 x^{3} y+x^{2} y^{2} \newlineC. x4+2x2y+y2 x^{4}+2 x^{2} y+y^{2}
  1. Identify formula: Identify the formula for binomial expansion (a+b)2=a2+2ab+b2(a+b)^2 = a^2 + 2ab + b^2. Here, a=x2a = x^2 and b=yb = y.
  2. Calculate each term: Calculate each term: (x2)2=x4(x^2)^2 = x^4, 2(x2)(y)=2x2y2(x^2)(y) = 2x^2y, and y2=y2y^2 = y^2.
  3. Compare with options: Compare the result with the options provided.
