Writing Polynomial Functions from Given Zeros
To write a polynomial function with given zeros, use the factored form where are the zeros. If the polynomial has rational coefficients and contains an irrational zero , then its conjugate must also be a zero. Key formulas include expressions such as P(x) = a(x - r_1)(x - r_2)...(x - r_n). This concept is part of Big Ideas Math, Algebra 2 for Grade 8 students, covered in Chapter 4: Polynomial Functions.
Key Concepts
To write a polynomial function with given zeros, use the factored form $P(x) = a(x r 1)(x r 2)...(x r n)$ where $r 1, r 2, ..., r n$ are the zeros. If the polynomial has rational coefficients and contains an irrational zero $a + b\sqrt{c}$, then its conjugate $a b\sqrt{c}$ must also be a zero.
