2. Factoring Equations Using the TI-Nspire CX

Factoring is a fundamental technique in algebra, often used to simplify expressions or solve quadratic equations. Here's how you can factor an expression using your TI-Nspire CX:

2.1 Adding the Calculator Functionality

1. Press the #x2B; key to open the math template palette.

2.2 Selecting the Factor Function

2. Navigate to the Menu button (third from the left in the top row of keys) and press it.

3. Select the Number tab in the menu.

4. Choose the Factor option from the menu. Your calculator display should now show Factor.

2.3 Inputting the Expression

5. Once you've selected Factor, type in the expression you want to factorize. For example, if you want to factorize (x^2 - 5x 6), enter the expression inside the parentheses.

2.4 Performing the Factorization

6. Press the Enter key to execute the factorization process. The calculator will display the factored form of your expression, which, in this case, would be (x - 2)(x - 3).

3. Using the Solve Function

The solve function in TI-Nspire CX is a powerful tool for finding the roots or solutions of equations. This function can be particularly useful for linear or quadratic equations, as well as other types of equations that require specific solutions.

3.1 Activating the Solve Function

1. To access the solve function, navigate to the Menu button (third from the left in the top row of keys) and press it.

2. Select the Algebra tab in the menu.

3. Choose the Solve option from the menu. Your calculator display should now show x.

3.2 Inputting the Equation and Variable

4. To use the solve function, you need to input the equation in the format axb, where the variable x is the unknown you want to solve for.

5. For example, if you want to solve the equation 2x 3 7, you would input the equation with the appropriate format.

6. Ensure that the equal sign () is present in the equation to denote the equality.

3.3 Executing the Solve Function

7. After entering the equation and variable, press the Enter key to solve for x. The TI-Nspire CX will provide you with the solution, which in this case would be x 2.
