How is the Fundamental Theorem of Algebra true for quadratic polynomials?
Are rational expressions closed under addition, subtraction, multiplication, and division?" ​

Answer 1

Polynomial identities apply to complex numbers by allowing us to perform operations, such as addition, subtraction, multiplication, and division. The Binomial Theorem uses Pascal's triangle to expand binomials raised to positive integer powers. The Fundamental Theorem of Algebra is true for quadratic polynomials because every quadratic polynomial has at least one complex root. Rational expressions are closed under addition, subtraction, multiplication, and division.

Step-by-step explanation:

Polynomial identities are equations that are true for all values of the variables in the polynomial. In the context of complex numbers, polynomial identities can be used to perform operations on complex numbers, such as addition, subtraction, multiplication, and division. For example, the identity (a + bi)(a - bi) = a^2 + b^2 can be used to find the product of two complex numbers in the form a + bi.

The Binomial Theorem is a formula that allows us to expand binomial expressions raised to positive integer powers. Pascal's triangle is a triangular array of numbers that can be used to determine the coefficients of the terms in the expanded expression. The coefficients can be found by reading the corresponding entries in Pascal's triangle. For example, to expand (x + y)^4, we can refer to the fourth row of Pascal's triangle, which contains the coefficients 1, 4, 6, 4, 1.

The Fundamental Theorem of Algebra states that every quadratic polynomial has at least one complex root. This means that every quadratic equation can be solved in the set of complex numbers. The complex roots of a quadratic polynomial can be found using the quadratic formula or by factoring the polynomial. For example, consider the quadratic polynomial x^2 + 2x + 1. By factoring, we can find that it is equal to (x + 1)^2, which means it has a double root at x = -1.

Rational expressions are expressions that can be written as the quotient of two polynomials. Rational expressions are closed under addition, subtraction, multiplication, and division. This means that when we perform these operations on rational expressions, the result is always a rational expression. For example, if we add two rational expressions, such as (3x + 2)/(2x^2 + 5x) and (4x - 1)/(2x - 1), the result is also a rational expression.
