Apolynomialof the second degree is generally called a quadratic polynomial. In elementary algebra, the quadratic formula is the solution of the quadratic equation. There are other ways to solve the quadratic equation instead of using the quadratic formula, such as factoring, completing the square, ...
What are the values of a, b, and c in the quadratic function f(x) = -2x^2 + 4x - 3 if f(x) = ax^2 + bx + c? Give an example of a quadratic function. What is c in the standard form of a quadratic function? What is b in a quadratic equation?
Quadratic equations are polynomial equations in the order of 2. In general, the solutions of polynomials are called zeroes or roots, which can be real or complex numbers.Answer and Explanation: Typically, the order or degree of a polynomial equation denotes the number of its possible roots. ...
