📘 Class 10 — Unit 20: Theory of Quadratic Equations Exercise 20.1 — Question 1 (Sindh Board) — Description In Exercise 20.1 Q1, students are asked to determine whether a given equation is a quadratic equation or not. A quadratic equation is an equation in the form: ax^2 + bx + c = 0 where: are real numbers (this is very important) 👉 If the equation contains a term with and the highest power of is 2, then it is a quadratic equation. 👉 If there is no term, or the highest power is not 2 (e.g., linear or cubic), then it is not quadratic. 🔍 What you need to do in Q1: Check each given equation. Rearrange if necessary to write it in standard form . Then decide whether it is quadratic. ✨ Key Tip: Sometimes equations are not in standard form like: 2x^2 - 3 = 0 \quad \text{or} \quad x(x+5) = 3 This question helps build a foundation for later topics like factorization, completing the square, and using the quadratic formula. --- #Class10Math #SindhBoard #QuadraticEquations #Exercise20_1 #MathLearning #MathX
