### Examples of how to use a precalculus calculator with steps to solve common problems:

Example 1: Solve the quadratic equation x^2 - 3x - 4 = 0.

Solution:

1. Enter the quadratic equation into the calculator.
2. Select the “Solve” button.
3. The calculator will display the following step-by-step solution:
Step 1: Factor the quadratic equation.



x^2 - 3x - 4 = (x - 4)(x + 1) = 0

Step 2: Set each factor equal to zero and solve for x.

x - 4 = 0
x = 4

x + 1 = 0
x = -1

Step 3: The solutions to the quadratic equation are x = 4 and x = -1.

Sure, here are some more examples of how to use a precalculus calculator with steps to solve common problems:

**Example 2:** Solve the polynomial equation x^3 - 2x^2 + x - 3 = 0.

**Solution:**

1. Enter the polynomial equation into the calculator.
2. Select the "Solve" button.
3. The calculator will display the following step-by-step solution:


Step 1: Use the Rational Root Theorem to find the possible rational roots of the polynomial.




The possible rational roots are: ±1, ±3




Step 2: Try each possible rational root in the polynomial to see if it is a solution.




x = 1 is a root of the polynomial.




Step 3: Use synthetic division to divide the polynomial by (x – 1).




The quotient is x^2 – x + 3.




Step 4: Factor the quotient.




x^2 – x + 3 = (x – 1)(x – 3)




Step 5: Set each factor equal to zero and solve for x.




x – 1 = 0 x = 1




x – 3 = 0 x = 3




Step 6: The solutions to the polynomial equation are x = 1 and x = 3.


Example 3: Solve the rational equation \frac{x}{x - 2} = \frac{x + 1}{x - 1}.

Solution:

1. Enter the rational equation into the calculator.
2. Select the "Solve" button.
3. The calculator will display the following step-by-step solution:


Step 1: Multiply both sides of the equation by the common denominator, x – 2.




x = x + 1




Step 2: Subtract x from both sides of the equation.




0 = 1




Step 3: There is no solution to the equation.


Example 4: Solve the exponential equation 2^x = 8.

Solution:

1. Enter the exponential equation into the calculator.
2. Select the "Solve" button.
3. The calculator will display the following step-by-step solution:


Step 1: Take the log of both sides of the equation.




log(2^x) = log(8)




Step 2: Use the rule of exponents to simplify the left side of the equation.




x * log(2) = log(8)




Step 3: Divide both sides of the equation by log(2).




x = \frac{log(8)}{log(2)}




Step 4: Use the calculator to evaluate the right side of the equation.




x = 3


Example 5: Solve the logarithmic equation log(x + 2) = 1.

Solution:

1. Enter the logarithmic equation into the calculator.
2. Select the "Solve" button.
3. The calculator will display the following step-by-step solution:


Step 1: Rewrite the equation in exponential form.




x + 2 = 10^1




Step 2: Subtract 2 from both sides of the equation.




x = 10^1 – 2




Step 3: Use the calculator to evaluate the right side of the equation.




x = 8 “`
