Explanation:
1. You can write the quadratic equation as following:
![f(x)=2x^(2)-10x+8](https://img.qammunity.org/2020/formulas/mathematics/middle-school/npgz629013jyvnl9yz2goewrmsginhiuhg.png)
2. Factor out 2. Then:
3. Now, you must find two number that when you add them you obtain -5 and when you multiply them you obtain 4. These would be -1 and -4.
3. Therefore, you can write the function in the following intercept form:
