Please mark me as the Brainliest

Step-by-step explanation:

The following rules apply: C = positive and B = positive; both factors have a + sign C = positive and B = negative; both factors have a – sign C = negative and B = positive; the factor with the largest value has a + sign C = negative and B = negative; the factor with the largest value has a - sign In the example ...
