Equations of the form: product=constant

This task focuses on equations one side of which is a product of linear functions and the other side a constant function. For example: (x + 2)(2x - 6) = 4.
You will create such equations with given properties.


Change one of the sides of the given equation to obtain a modified equation with certain properties. If you think it cannot be done, explain why.

Begin with the equation:




(1) Leave the left side as is and change the right side to different constant functions to obtain equations with the following properties:


 
An equation with one positive solution and one negative solution.
  • An equation with two negative solutions.
  • An equation in which one of the solutions is 4.
  • An equation in which one of the solutions is 5.
  • An equation that has no solution.
  • An equation that has only one solution.
  • An equation in which the solutions are 1 and 9.
  • An equation in which the solutions are 3 and 11.

  • (2) Again, starting with the equation (x - 4)(x - 6) = 8:

    Leave the right side as is and change the left side to other functions that are products of linear functions, to obtain equations with the properties listed above.
