(a+b)^2
and select the =
(e.g. y = 2*x
), while the input :=
indicates an assignment (e.g. f(x) := 2*x
).
Note: This means that the input a = 2
will not assign value 2 to the variable a.

or a space between the factors.
1. | ![]() | Enter (x - 2) (x + 1) into the Input Bar of the ![]() |
2. | ![]() | Evaluate your input using the Symbolic Evaluation tool.
Note: Your expression is simplified and displayed as x² - x - 2 in the output display. |
4. | ![]() | Keep your input using the Keep Input tool.
Note: Your expression is not changed and will be displayed as (x - 2) (x + 1) in the output display.
|
5. | ![]() | Create a quadratic polynomial by entering f(x):= x^2 – 3/2 * x + 2 into the first row and select the Keep Input tool instead of pressing the Enter key. |
6. | | Note: If you want your entered expression not to be changed in any way, choose the tool before entering it. |
7. | ![]() | Enter f(x) into the second row and select the Factor tool to find the factors of the function. |
8. | ![]() | Enter f(x) into the third row and select the Derivative tool to calculate the derivative of the function. |
9. | ![]() | Hint: You can display the function in the ![]() ![]() |
