General Form of an A.P:
Let us consider a series with n number of terms:
a1 + a2 + a3 + a4 + a5 + a6 + a7 …………………………….. = an
The above series of numbers is said to form an Arithmetic Progression (A.P) if,
a2 – a1 = a3 – a2 = a4 – a3 = …………………………. […]
Polynomials with degree 2 are called quadratic polynomials. When this polynomial is equated to zero, we get a quadratic equation.
Its general form is a2 + bx + c = 0, where a, b and c are real numbers and a ≠ 0.
In many real life situations we deal with quadratic equations.
Suppose, we have to make […]
Astitva tells his daughter, “Seven years ago I was seven times as old as you were then and also three years from now, I shall be three times as old as you will be.” Represent this situation algebraically and graphically.
Let the present age of Astitva be ‘x’.
And, the present age of his daughter be […]
DEGREE OF A POLYNOMIAL:-
If p(x) is a polynomial in x, the highest power of x in p(x) is called the degree of polynomial p(x).
And expressions like:- x2−−√+
Use Euclid’s division algorithm to find the HCF of:
i)135 and 225
ii)196 and 38220
iii)867 and 225
i) We start with the larger number i.e 225
By Euclid’s division algorithm,we have
