### 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:**

- Enter the quadratic equation into the calculator.
- Select the “Solve” button.
- 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 “`
