In the standard form of a quadratic equation describing a parabola, which term represents the squared variable?

• A. The x term
• B. The constant term
• C. The x^2 term
• D. The square root term

Answer: (C)

In a quadratic equation written as ax^2 + bx + c, the term that carries x squared is the one with x^2. This is the squared variable part, since x is multiplied by itself. The bx term has x to the first power (the linear term), and c is the constant term (a plain number). The x^2 term, multiplied by the coefficient a, is what shapes the parabola.
