Three polynomials are factored below, but some coefficients and constants are missing. All of the missing values of a, b, c, and d are integers.
1. x2 + 2x - 8 = (ax + b)(cx + d)
2. 2x3 + 2x? - 24x = 2x(ax + b)(cx + d)
3. 6x? - 15x - 9 = (ax + b)(ex + )
Fill in the table with the missing values of a, b, c, and d.
