Polynomials

Answer

A polynomial is an algebraic expression in which the powers of all variables are whole numbers (0, 1, 2, 3, ...). For example: x³ + 2x² - 5x + 7 is a polynomial, but √x + 5 and 1/x - 3 are not polynom

Answer

The degree of a polynomial in one variable is the highest power of the variable in the polynomial. Example: In p(x) = 2x⁷ - 5x + 9, the highest power is 7, so the degree is 7. For constant polynomials

Answer

For polynomials with multiple variables, the degree is the highest sum of powers of variables in any single term. Example: In 3m³n⁶ + 7m²n³ - mn, the degrees of terms are: 3+6=9, 2+3=5, 1+1=2. The hig

Answer

A constant polynomial contains only a constant term with no variables. Examples: 6, -7, 1/2, √3. The degree of any non-zero constant polynomial is 0 because we can write it as 6 = 6x⁰. The degree of z

Answer

Monomial: Polynomial with one term. Example: 5x³. Binomial: Polynomial with two terms. Example: 3x² + 7. Trinomial: Polynomial with three terms. Example: x² - 4x + 3. These classifications are based o

Answer

Degree 0: Constant polynomial (Example: 5). Degree 1: Linear polynomial (Example: 2x + 3). Degree 2: Quadratic polynomial (Example: x² + 5x + 6). Degree 3: Cubic polynomial (Example: x³ - 2x + 1). Deg

Answer

Standard form of a polynomial is when terms are arranged in descending order of powers of the variable. Example: x - 3x² + 5 + x⁴ in standard form becomes x⁴ - 3x² + x + 5. The terms are arranged from

Answer

Index form includes all missing terms with coefficient zero. Example: x⁴ - 3x² + x + 5 in index form is x⁴ + 0x³ - 3x² + 1x + 5. This form shows every power from the highest degree down to the constan
