19/04/21 (Monday)
Topic Taught:
3. A polynomial of two terms is called a binomial.
4. A polynomial of three terms is called a trinomial.
5. A polynomial of degree one is called a linear polynomial.
6. A polynomial of degree two is called a quadratic polynomial.
7. A polynomial of degree three is called a cubic polynomial.
8. A real number ‘a’ is a zero of a polynomial p(x) if p(a) = 0. In this case, a is also called a root of the equation p(x) = 0.
9. Every linear polynomial in one variable has a unique zero, a non-zero constant polynomial has no zero, and every real number is a zero of the zero polynomial.

Topic Taught:
Zeroes of the Polynomial
Finding the value of f(x) at given values of x
Substitute the value of x in f(x) to find the value
Finding zeroes of polynomial
Equate f(x) =0 to find the zero of polynomial f(x)
Checking whether given value of x is a root of f(x) or not:
If f(x) = 0 , then x is said to be a zero of f(x)
