I will show you the steps on how you get that answer and if you have any questions after that let me know and I'd be more than happy to help answer them for you. The first step for solving (1 + y)² is to use the equation (a + b)² = a² + 2ab + b² to expand the expression. 1² + 2 × 1y + y² 1 raised to any power equals 1,, so remove the power. 1 + 2 × 1y + y² Calculate the product of 2 × 1y. 1 + 2y + y² Finally,, use the commutative property to reorder the terms. y² + 2y + 1 Let me know if you have any further questions. :)
