Mathematics
1 answer:
vodka [1.7K]3 years ago
3 0

Answer:

There are some unknown characters in the answer list, so am not certain which letter. However, the expansion of (x^2 + y)^2 is:

x^4 + 2yx^2 + y^2.

Note: Am using the carrot - shift 6 - ^ to denote "to the power of".

Step-by-step explanation:

(x^2 + y)^2 = (x^2 + y) * (x^2 + y)

                  = (x^2 * x^2) + (y*x^2) + (y*x^2) + (y * y)

                  = x^4 + 2yx^2 + y^2

In words the answer is: x to the 4th plus 2 yx squared plus y squared.
