Study Plan
Learn the Theory
Read the textbook chapter carefully. Note down definitions, formulas and key ideas. Focus on: 1. Basic Meaning and Standard Form, 2. Discriminant and Nature of Roots, 3. Graph of a Quadratic Function.
Practise
Solve the textbook exercises and extra practice questions. There are 104 questions available for this chapter.
Revise & Test
Revise key points without looking at your notes. Take a practice quiz and mark weak areas for another pass.
Spaced Revision
Come back to Quadratic Equations after a week. Use flashcards for quick recall and try past exam questions on this chapter.
What to Focus On
- Quadratic equation: ax^2 + bx + c = 0, a != 0
- Roots are values of x that satisfy the equation
- A quadratic equation has exactly two roots
- Quadratic formula: x = (-b ± sqrt(b^2 - 4ac)) / (2a)
- Discriminant: D = b^2 - 4ac
- D > 0 gives real and distinct roots
- Always identify a, b, c carefully
- Use the discriminant first to predict the nature of roots
- If D is negative, the roots are complex
Common Mistakes to Avoid
Every quadratic equation with real coefficients has two real roots.
A quadratic equation is any equation with x^2 in it, even if a is zero or the equation is not equal to zero.
The discriminant only tells whether roots exist, not whether they are real, equal, or complex.
