Exercises 26 Chapter 3. To solve a cubic equation, start by determining if your equation has a constant. In this section, we will review a technique that can be used to solve certain polynomial equations. We put in the value of the independent variable and try to get the value of expression equal to zero. Roots of Quadratic Polynomial. After factoring the polynomial of degree 5, we find 5 factors and equating each factor to zero, we can find the all the values of x. A polynomial function is an expression which consists of a single independent variable, where the variable can occur in the equation more than one time with different degree of the exponent. I can guess #4 by dividing both sides by y to get 8y^3-1=0 or y^3 = 1/8 or y = 1/2. Different kind of polynomial equations example is given below. Quadratic Equation: (2x + 1)2 − (x − 1)2 = 21. f(x) = ax 3 + bx 2 + cx + d where "a" is nonzero. Roots of Quadratic Polynomial. A polynomial equation of degree 1 is a linear equation and such equations have been solved in Section 3.1. Solving Polynomial Equations. Create a vector . A necessary and sufficient condition for a polynomial Diophantine equation to have a solution is for c to be a multiple of the GCD of a and b.
