#### Main Point on 10th Maths Chapter 1

Euclid’s Division Lemma: Given two positive integers a and b, there exist unique integers q and r satisfying a = bq + r, 0 ≤ r < b.
Euclid’s Division Algorithm to obtain the HCF of two positive integers, say c and d, c > d.

Fundamental Theorem of Arithmetic: Every composite number can be expressed as a product of primes, and this expression (factorisation) is unique, apart from the order in which the prime factors occur.

Let p be a prime number. If p divides square of a, then p divides a, where a is a positive integer.

Square root of 2, 3, 5 are irrational numbers.

The sum or difference of a rational and an irrational number is irrational.

The product or quotient of a non-zero rational number and an irrational number is irrational.

For any two positive integers a and b, HCF (a, b) × LCM (a, b) = a × b.

##### Main Point on 10th Maths Chapter 2

Geometrical meaning of zeroes of a polynomial: The zeroes of a polynomial p(x) are precisely the x-coordinates of the points where the graph of y = p(x) intersects the x-axis.

Relation between the zeroes and coefficients of a polynomial: If α and β are the zeroes of a quadratic polynomial ax2 + bx + c, then α + β = -b/a and αβ = c/a.

The division algorithm states that given any polynomial p(x) and any non-zero polynomial g( x), there are polynomials q(x) and r(x) such that p(x) = g(x) q(x) + r(x), where r(x) = 0 or degree r(x) < degree g(x).
