The binomial expansion of (x^2+y)^2 is?

x⁴+2x²y+y²

Step-by-step explanation:

Given the equation( x²+y)², to expand, we will open the bracket by multiplyimg the function x²+y by itself to have;

(x²+y)² = (x²+y)(x²+y)

(x²+y)² = x⁴+x²y+x²y+y²

(x²+y)² = x⁴+2x²y+y²

Therefore the expansion form of (x²+y)² is x⁴+2x²y+y²
