A polynomial is an expression with variables and coefficients, using only addition, subtraction, multiplication, and non-negative integer exponents.
The degree is the highest power of the variable. For example, x³ + 2x² + 3x + 1 has degree 3.
Roots (zeros) are values of x that make the polynomial equal to zero. A polynomial of degree n has at most n roots.
Factoring breaks a polynomial into a product of simpler polynomials, which helps find roots and simplify expressions.
x² - 5x + 6 = 0 → x = 2, x = 3
x² - 4 = (x + 2)(x - 2)
(x² + 2x + 1) + (x² + 3x + 2) = 2x² + 5x + 3
f(x) = x² + 2x + 1, f(3) = 16
A polynomial is a mathematical expression consisting of variables and coefficients, involving only addition, subtraction, multiplication, and non-negative integer exponents.
The roots (zeros) of a polynomial are the values of x that make the polynomial equal to zero. For quadratic polynomials, you can use the quadratic formula.
The degree of a polynomial is the highest power of the variable in the polynomial. For example, x³ + 2x² + 3x + 1 has degree 3.
