The idea

What is Quadratic equations?

Quadratic equations are equations in which the highest power of the unknown is two, written in the standard form ax squared plus bx plus c equals zero with a not zero. Their graph is a parabola, and the solutions, called roots, are where that parabola crosses the horizontal axis. Roots are found by factorising, completing the square or the quadratic formula, and the discriminant b squared minus 4ac tells you whether there are two real roots, one repeated root, or none.

Where it appears: Class 10 and 11 CBSE and ICSE, GCSE and IGCSE, IB Mathematics, SAT, JEE foundation.

Where learners get stuck

Why Quadratic equations is hard

Learners often treat the discriminant as a separate rule rather than the part of the formula under the square root, and forget that a negative discriminant simply means the parabola never touches the x-axis.

The picture a good explanation starts with: A parabola drawn on x and y axes, its two crossing points on the x-axis circled and labelled as the roots, with the vertex marked between them.

A lesson, step by step

How a lesson on Quadratic equations goes

  1. 01

    Ask

    Type or say "Why does the quadratic formula have a plus or minus sign?" in your own words, in any of 26 languages.

  2. 02

    Plan

    The tutor plans a storyboard, one picture per idea, starting with a parabola drawn on x and y axes, its two crossing points on the x-axis circled and labelled as the roots, with the vertex marked between them.

  3. 03

    Explain

    It explains Quadratic equations out loud while the picture builds step by step, pitched to your level (Class 10 and 11 CBSE and ICSE and up).

  4. 04

    Interrupt

    Say "wait, why?" or type a doubt: it stops, answers over the picture, and carries on. Ask for a different explanation any time.

  5. 05

    Check

    A checkpoint question makes sure the idea landed, and Test Lab keeps the practice going.

  6. 06

    Your notes

    Upload a PDF or a photo of your class notes or a past paper and the lesson follows your textbook's terms.

Ask it anything

Questions learners ask about Quadratic equations

  • Why does the quadratic formula have a plus or minus sign?
  • How do I know which factorising method to use?
  • Can a quadratic equation have no solution at all?

Any of these, or your own, typed or spoken. The tutor answers on the picture and adapts to how well you are following.

Questions

Asked, Answered

Can LetMeTeach explain Quadratic equations?

Yes. Ask in your own words and the tutor plans a lesson on Quadratic equations: it starts with a parabola drawn on x and y axes, its two crossing points on the x-axis circled and labelled as the roots, with the vertex marked between them. Then it explains each step out loud as the picture builds, stops when you say "wait, why?", and ends with a checkpoint question.

Where does Quadratic equations come up?

Class 10 and 11 CBSE and ICSE, GCSE and IGCSE, IB Mathematics, SAT, JEE foundation. The lesson is pitched to your level and the exam or curriculum you follow, and you can upload your own notes or past papers so it uses your textbook's terms.

Can I learn Quadratic equations in my own language?

Yes. LetMeTeach teaches in 26 languages and plans the lesson in the language you choose rather than translating an English one, so the terms match what your textbook says. The Free plan includes 7 hours a month with no card.
