HP Board Class 10 Maths| First 4 Chapters Important Questions,100% score,exam me aane vale questions

Summary

The video presents a study guide for the first four chapters of HP Board Class 10 Mathematics. The presenter predicts likely exam topics and question types based on their experience and references to textbooks, model papers, and previous papers.

These are predictions, not guaranteed exam questions. The presenter also uses an older textbook, so exercise and question numbering may differ from current editions.

1. Real Numbers — Estimated 6 Marks

• MCQs: Review how to find the HCF and LCM of two numbers, and remember:
  • HCF × LCM = product of the two numbers
• Prime factorisation: Practise finding the prime factors of numbers.
• Textbook exercises: Review questions around 1–4 in Exercise 1.1, particularly those involving the HCF–LCM relationship.
• Irrationality proofs: Practise proving that numbers such as √2, √3, or √5 are irrational. The presenter says the same basic method applies, with the number changed.

2. Polynomials — Two MCQs Expected

• Learn to identify a polynomial’s number of zeros from its graph by counting where the graph meets or crosses the x-axis.
• Learn the formulas connecting the sum and product of zeros with the coefficients of a quadratic polynomial.
• Practise using those formulas to find the sum or product of zeros.
• The presenter recommends focusing on understanding the concepts and checking answers rather than spending time on less-emphasised material.

3. Pair of Linear Equations in Two Variables — Estimated 15 Marks

The presenter describes this as a particularly important chapter. They expect questions involving:

• Graphs and consistency: Learn to graph pairs of linear equations and determine whether the pair is consistent or inconsistent (also described as compatible or incompatible).
• Solving methods: Practise solving systems using the substitution and elimination methods.
• Long-answer questions: The presenter predicts two five-mark questions, along with shorter questions. They recommend working through several textbook problems, since the same methods apply even when the equations change.
• The presenter suggests that strong preparation in this chapter may reduce the need to rely on a related question from Chapter 9. This is exam advice, not a certainty.

4. Quadratic Equations — Estimated 9 Marks

• Solving equations: Practise solving quadratic equations, including problems from the exercises highlighted by the presenter. Questions around numbers 3–5 are singled out, along with selected earlier questions.
• Discriminant and roots: Learn the discriminant:
  • D = b² − 4ac
  • If D > 0, the equation has two distinct real roots.
  • If D = 0, it has equal real roots.
  • If D < 0, it has no real roots.
• MCQ preparation: The presenter expects an MCQ on the discriminant or a related quadratic-equation concept.
• Word problems: Practise forming and solving quadratic equations for situations involving sums and products, consecutive integers, and a triangle-related problem.

Overall Advice

The presenter estimates that the four chapters together account for 32 marks. Their general recommendation is to learn the underlying methods and concepts—not just memorise question numbers—and to practise the highlighted textbook problems. The marks and predictions may not match the final exam or a newer textbook edition.
