❓Frequently Asked Questions
What is a linear equation?
A linear equation is an equation where the variable (x) appears only to the first power. It typically takes the form ax + b = c, where a, b, and c are numbers.
What is a quadratic equation?
A quadratic equation contains x², and takes the form ax² + bx + c = 0. It can have zero, one, or two solutions depending on its discriminant (b² - 4ac).
How do you solve linear equations?
Linear equations are solved by isolating x on one side. This involves moving all other terms to the opposite side and then dividing both sides by the coefficient of x.
What is the quadratic formula?
The quadratic formula is x = (-b ± √(b² - 4ac)) / (2a), where a, b, and c are the coefficients in the standard form ax² + bx + c = 0.
What are complex solutions?
Complex solutions occur in quadratic equations when the discriminant (b² - 4ac) is negative. They involve the imaginary unit i, where i² = -1.
How do I enter equations?
For linear equations, enter in the form "ax + b = c" (e.g., 2x + 3 = 7). For quadratic equations, enter in the form "ax² + bx + c = 0" (e.g., x² + 2x - 3 = 0).
