Question

if the cost price of certain pens is 6x³-x²-11x+6 and cost price of each pen is Re(2x+3) find the number of pens in an algebraic expression​

Answer 1

Answer:

3x^2-5x+2

Step-by-step explanation:

6x^3-x^2-11x+6 ÷ 2x+3 = 3x^2-5x+2

Answer 2

Number of Pens =  3x² - 5x + 2 if cost price of certain pens is 6x³-x²-11x+6 and cost price of each pen is Rs(2x+3)

Step-by-step explanation:

cost price of certain pens is 6x³-x²-11x+6

cost price of each pen is (2x+3)

Let say Number Of Pens = Y

Then Cost of all pens = Cost of 1 Pen  * Number of Pens

=> 6x³-x²-11x+6 =  (2x+3) * Y

=> Y =  (6x³-x²-11x+6 ) /(2x + 3)

                                      3x² - 5x + 2

               2x+ 3        _|   6x³ -  x² - 11x + 6  |_

                                      6x³ + 9x²

                                    ____________

                                               -10x²  - 11x  + 6

                                               -10x²  - 15x

                                               _____________

                                                           4x + 6

                                                           4x + 6

                                                         _________

                                                                  0

                                                         _____________

Number of Pens =  3x² - 5x + 2
