Use the long division to find the other factor of the function
Writing the function as product of factors
To set up the third zero of the polynomial, set the factor
- Subtracting 3 to both sides of the equation, and then
- Simplifying on both sides of the equation, and then
- Dividing 2 on both sides, and then
- Simplifying fraction on both sides of the equation
