I got the question wrong. I have a question regarding that one… Why did you consider a and b negative while considering Example 2 page 142 a,b, and c ( PWN Math Study Guide 4th edition) positive?

The trick is where the zeros are. In that example in my book, all the zeros are negative. In this example, you have one negative zero and two positive zeros.
