### MM1A2: Students will simplify and operate with radical expressions, polynomials, and rational expressions.

#### MM1A2.e: Factor expressions by greatest common factor, grouping, trial and error, and special products limited to the formulas below.

MM1A2.e.1: (x + y)² = x² + 2xy + y²

MM1A2.e.2: (x - y)² = x² - 2xy + y²

MM1A2.e.3: (x + y)(x - y) = x² - y²

MM1A2.e.4: (x + a)(x + b) = x² + (a + b)x + ab

MM1A2.e.5: (x + y)³ = x³ +3x²y + 3xy² + y³

MM1A2.e.6: (x – y)³ = x³ –3x²y + 3xy² - y

### MA1A2: Students will simplify and operate with radical expressions, polynomials, and rational expressions.

#### MA1A2.e: Factor expressions by greatest common factor, grouping, trial and error, and special products limited to the formulas below.

MA1A2.e.1: (x + y)² = x² + 2xy + y²

MA1A2.e.2: (x – y)² = x² – 2xy + y²

MA1A2.e.3: (x + y)(x – y) = x² – y²

MA1A2.e.4: (x + a)(x + b) = x² + (a + b)x + ab

MA1A2.e.5: (x + y)³ = x³ + 3x²y + 3xy² + y³

MA1A2.e.6: (x – y)³ = x³ – 3x²y + 3xy² – y³

### MA3D2: Using student-generated data from random samples of at least 30 members, students will determine the margin of error and confidence interval for a specified level of confidence.
