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
1.2 - 2x - 15 = (ax + b)(ex + d)
2. 2x2 - 6x2 – 36r = 2x(ax + b)(ex + d)
3. 422 + 10x + 4 = (ax + b)(ex + d)
Fill in the table with the missing values of a, b, c, and d.
