Study Plan

1
Day 1–2

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.

2
Day 3

Practise

Solve the textbook exercises and extra practice questions. There are 104 questions available for this chapter.

3
Day 4

Revise & Test

Revise key points without looking at your notes. Take a practice quiz and mark weak areas for another pass.

Day 7

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.
