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
Answers
Answer:
3x^2-5x+2
Step-by-step explanation:
6x^3-x^2-11x+6 ÷ 2x+3 = 3x^2-5x+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
____________
