The product of a and c is -180 and b is −31. We must find the factors of -180 that sum to -31, so we can replace -31x in the quadratic with two terms. In this case, the product ac is negative and b is negative, so the factor with the greater absolute value will be negative and the other factor will be positive. Some of the pairs of integers whose product is -180 with negative sums, are as follows. Factors of -180 Sum of factors 5, 4, -45 6, -30 -41 000
