Irrational Conjugates Theorem
If a polynomial has rational coefficients and is a zero (where and are rational and is irrational), then must also be a zero. Key formulas include expressions such as a + b\sqrt{c}. This concept is part of Big Ideas Math, Algebra 2 for Grade 8 students, covered in Chapter 4: Polynomial Functions.
Key Concepts
If a polynomial has rational coefficients and $a + b\sqrt{c}$ is a zero (where $a$ and $b$ are rational and $\sqrt{c}$ is irrational), then $a b\sqrt{c}$ must also be a zero.
