Explanation Given: The polynomial R ( x ) = 1810 x − 81 x 2 − x 3 represents revenue function with x is the number of units sold. When 9 units are sold, the total revenue will be $9000. Procedure used: Synthetic division method: “To divide a polynomial by ( x − a ) : 1. Arrange the coefficients in descending powers of x , with a 0 for any missing power. Place a from ( x − a ) to the left of the coefficients. 2. Bring down the first coefficient to the third line. Multiply the last number in the third line by a and write the product in the second line under the next term. 3. Add the last number in the second line to the number above it in the first line. Continue this process until all numbers in the first line are used. 4. The third line represents the coefficients of the quotient, with the last number the remainder. The quotient is a polynomial of degree one less than the dividend. If the remainder is 0, x − a is a factor of the polynomial, and the polynomial can be written as the product of the divisor x − a and the quotient.” Calculation: The sale of 9 units gives a total revenue of $9000. That is, x = 9 will satisfy the equation R ( x ) = 9000 . R ( x ) = 9000 − x 3 − 81 x 2 + 1810 x = 9000 − x 3 − 81 x 2 + 1810 x − 9000 = 0 Thus, the value of x = 9 is the solution of the equation − x 3 − 81 x 2 + 1810 x − 9000 = 0 . That is, the term x − 9 is a factor of the polynomial − x 3 − 81 x 2 + 1810 x − 9000 . Divide the polynomial − x 3 − 81 x 2 + 1810 x − 9000 by x − 9 . Set the coefficients in descending powers of x , − 1 − 81 1810 − 9000 Set 9 from x − 9 to the left of the coefficients. 9 − 1 98 − 700 − 1800 Use step 2 and 3 mentioned in Synthetic division method and bring –1 to the last entry (that is, last from the right end) of third line and multiply –1 by a , which is 9 and write the product –9 in second line under next term and add the number –9 in the second line and the number above –81 in first line

Solve the linear system of equations attached using Gaussian elimination (not Gauss-Jordan) and back subsitution. Remember that: A matrix is in row echelon form if Any row that consists only of zeros is at the bottom of the matrix. The first non-zero entry in each other row is 1. This entry is called aleading 1. The leading 1 of each row, after the first row, lies to the right of the leading 1 of the previous row.
