the initial price of a stock was x dollars. write an expression that represents the price of the stock at the end of the second week, the first week of trading the price gained x^2-x+4 dolllars and the next week it lost 2x^2+ x-2 dollars

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
