Answer:
Let's expand those expressions.
1) To expand (a² + b)(a + b²), we can use the distributive property.
(a² + b)(a + b²) = a(a² + b) + b²(a + b²)
= a³ + ab + b²a + b³
2) For (x + y)(x² - xy + y²), we can also use the distributive property.
(x + y)(x² - xy + y²) = x(x² - xy + y²) + y(x² - xy + y²)
= x³ - x²y + xy² + xy² - xy³ + y³
= x³ - x²y + 2xy² - xy³ + y³
So, the expanded forms are:
1) a³ + ab + b²a + b³
2) x³ - x²y + 2xy² - xy³ + y³
