Final answer:
Quadratic equations, being second-order polynomials, usually have two solutions. These solutions can be found either by a step-by-step algebraic process or by using a TI-83 or TI-84 series calculator function.
Step-by-step explanation:
The solutions to a quadratic equation can be found using different methods, one of which is the step-by-step solution (Solution A) and the other is using the function of a TI-83, TI-83+, or TI-84 calculator (Solution B). Quadratic equations are a type of second-order polynomials and they usually have two solutions. To solve for these solutions, one must:
- Identify the unknown variable in the equation.
- Identify the known values that are given in the problem.
- Select the appropriate quadratic equation or function to solve for the unknown.
Once these steps are followed, the quadratic equation can be solved either algebraically or with the aid of a calculator, yielding up to two solutions due to the nature of squared unknowns.
