Now we can substitute terms into our friend the quadratic equation, which you should memorize. Or we can try a few simple factors. 7 is prime, so to make -7 one number must be positive and one must be negative.
The first pair I tried, (2x + 1)(2x - 7) yield a middle term of -12x. Therefore, setting each to zero yields: x = -1/2, or x = 7/2.
There isn't an obvious question to this problem but with the given we can assume what is to be asked. I think we are to find the total cost of a certain poultry seasoning. The poultry seasoning would have a total weight of 4+2=6 ounces. The total cost will then have to be 4(4) + 2(3) = 22 dollars.
