What Really Is X?
Quadratic equations are special math problems that involve a variable (let’s call it ‘x’) being squared, or raised to the power of two. They have a specific format, which looks like this:
x² + bx + c = 0
Here, ‘b’ and ‘c’ are numbers, and ‘x’ is the variable we’re trying to figure out. The goal is to find the value or values of ‘x’ that make the equation true.
When we graph a quadratic equation on a coordinate plane, it creates a curve called a parabola. Think of it as a U-shape or an upside-down U-shape.
Quadratic equations have been studied for a very long time because they’re super useful in many areas, like science, engineering, and even in computer programs.
