Important Points to Remember – Class 10 Maths

• Euclid’s Division Algorithm states that for any positive integers a and b, a = bq + r where 0 ≤ r < b, and is used to find HCF of two positive integers
• The Fundamental Theorem of Arithmetic proves that every composite number can be expressed as a product of primes in a unique way
• A rational number p/q has terminating decimal expansion if and only if the prime factorisation of q contains only powers of 2 and 5
• Linear polynomials have degree 1 (like 2x – 3), quadratic polynomials have degree 2 (like ax² + bx + c, a ≠ 0), and cubic polynomials have degree 3
• If p(x) is a polynomial and p(k) = 0 for some real number k, then k is called a zero of the polynomial p(x)
• A pair of linear equations in two variables can have: unique solution (intersecting lines), no solution (parallel lines), or infinitely many solutions (coincident lines)
• For pair of linear equations a₁x + b₁y + c₁ = 0 and a₂x + b₂y + c₂ = 0: if a₁/a₂ ≠ b₁/b₂, then unique solution exists
• A quadratic equation is of the form ax² + bx + c = 0 where a, b, c are real numbers and a ≠ 0
• The discriminant of a quadratic equation ax² + bx + c = 0 is Δ = b² – 4ac, which determines the nature of roots
• If discriminant > 0, roots are real and distinct; if discriminant = 0, roots are real and equal; if discriminant < 0, no real roots exist
• Sum of roots of quadratic equation ax² + bx + c = 0 is -b/a and product of roots is c/a
• Irrational numbers like √2, √3, √5 can be proved irrational using the Fundamental Theorem of Arithmetic by contradiction method
• The degree of zero polynomial is undefined, and every non-zero constant polynomial has degree zero
• Substitution method, elimination method, and cross-multiplication method are three algebraic methods to solve linear equations in two variables
• Completing the square method transforms quadratic equation ax² + bx + c = 0 into perfect square form for easy solving

Quick Revision Notes – Class 10 Maths

• Remember that HCF can be found using Euclid’s Division Algorithm by repeatedly applying division until remainder becomes zero – the last non-zero remainder is HCF
• For proving irrationality of numbers like √2, assume it’s rational (p/q form), square both sides, use Fundamental Theorem of Arithmetic to show contradiction
• Quick check for terminating decimals: after reducing fraction to lowest terms, if denominator has only 2ⁿ × 5ᵐ form, decimal terminates
• Polynomial division follows same rules as number division – use long division method when dividing polynomial by another polynomial of lower degree
• Zeros of polynomial p(x) are x-intercepts of graph y = p(x) – quadratic polynomial can have maximum 2 zeros, cubic can have maximum 3
• For graphical solution of linear equations, plot both lines and find intersection point – use at least 3 points per line for accuracy
• In elimination method, make coefficients of one variable equal by multiplying equations with suitable numbers, then add/subtract to eliminate
• Cross-multiplication method for a₁x + b₁y + c₁ = 0 and a₂x + b₂y + c₂ = 0 gives x/(b₁c₂ – b₂c₁) = y/(c₁a₂ – c₂a₁) = 1/(a₁b₂ – a₂b₁)
• For word problems on quadratic equations, carefully define variable, form equation from given conditions, then solve using appropriate method
• Quadratic formula derivation by completing square is important for board exams – practice the complete step-by-step process
• Nature of roots questions are common in boards – memorize discriminant conditions and relationship between coefficients and roots
• Factorization method works when quadratic can be written as product of linear factors – look for two numbers that multiply to ‘ac’ and add to ‘b’
• Application problems on quadratic equations often involve area, time-speed-distance, profit-loss scenarios – practice identifying the quadratic relationship
• Board exams frequently ask to find polynomial when zeros are given – use sum and product relationships to construct the equation
• Graphical representation questions require proper labeling of axes, scale, and intersection points – practice plotting linear and quadratic graphs
