Answer:
f(x)=2(x-1)(x-4)


Explanation:

1. You can write the quadratic equation as following:


f(x)=2x^(2)-10x+8

2. Factor out 2. Then:


f(x)=2(x^(2)-5x+4)

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:


f(x)=2(x-1)(x-4)
