Solving Equations and Inequalities

The TI-30Xs can be used to solve a variety of equations and inequalities. This section will provide instructions on how to solve linear equations, quadratic equations, trigonometric equations, and systems of equations.

Solving Linear Equations

A linear equation is an equation of the form `ax + b = 0`, where `a` and `b` are real numbers and `x` is the variable. To solve a linear equation, you can use the following steps:

1. Isolate the variable. This means that you need to get `x` by itself on one side of the equation.
2. Use the distributive property to multiply both sides of the equation by the reciprocal of `a`. This will clear the fraction on the left side of the equation.
3. Solve for `x`. This means that you need to find the value of `x` that makes the equation true.

Here is an example of how to solve a linear equation using the TI-30Xs:

“`
Solve 2x + 3 = 11
“`

1. Isolate the variable. Subtract 3 from both sides of the equation:

“`
2x + 3 – 3 = 11 – 3
“`

2. Use the distributive property to multiply both sides of the equation by the reciprocal of 2. This will clear the fraction on the left side of the equation:

“`
(2x + 3 – 3) / 2 = 11 – 3 / 2
“`

3. Solve for `x`. Simplify the right side of the equation:

“`
(2x – 3) / 2 = 8 / 2
“`

4. Divide both sides of the equation by 1. This will give you the value of `x`:

“`
x = 4
“`

Solving Quadratic Equations

A quadratic equation is an equation of the form `ax^2 + bx + c = 0`, where `a`, `b`, and `c` are real numbers and `x` is the variable. To solve a quadratic equation, you can use the following steps:

1. Find the discriminant. The discriminant is a number that is used to determine the number of solutions to a quadratic equation. The discriminant is calculated by squaring the coefficient of `x` and subtracting it from four times the product of the coefficients of `x^2` and `c`.
2. Use the quadratic formula to solve the equation. The quadratic formula is a formula that can be used to find the solutions to a quadratic equation. The quadratic formula is:

“`
x = (-b (b^2 – 4ac)) / 2a
“`

3. Check your solutions. To check your solutions, substitute them back into the original equation. If the solutions make the equation true, then they are correct.

Here is an example of how to solve a quadratic equation using the TI-30Xs:

“`
Solve x^2 – 4x + 3 = 0
“`

1. Find the discriminant. The discriminant is calculated by squaring the coefficient of `x` and subtracting it from four times the product of the coefficients of `x^2` and `c`.

“`
= (-4)^2 – 4(1)(3) = 16 – 12 = 4
“`

2. Use the quadratic formula to solve the equation. The quadratic formula is:

“`
x = (-b (b^2 – 4ac)) / 2a
“`

“`
x = (-(-4) (4^2 – 4(1)(3))) / 2(1)
“`

“`
x = (4 16) / 2
“`

“`
x = (4 4) / 2
“`

“`
x = 2, 2
“`

3. Check your solutions. To check your solutions, substitute them back into the original equation.

“`
(2)^2 – 4(2) + 3 = 4 – 8 + 3 = 1
“`

“`
(2)^2 – 4(2) + 3 = 4 – 8 + 3 = 1
“`

Both solutions make the equation true,
