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 - 15 = (ax + b)(cx + d)
2.2r? + 6x2 - 20x = 2x(ax + b)(x + d)
3.9x2 + 21x + 6 = (ax + b)(cx + d)
Fill in the table with the missing values of a, b, c, and d.

divide using polynomial division.

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33

ok so what's the question?
