It is also explained that the value of the polynomial and if the value is 0, then it is called 0 polynomial. As it is already clear that the zero polynomial is a polynomial whose value is zero. In addition to the ordinary polynomials, the zero polynomial is very important when compared to the other. Because while plotting a graph for the zero quadratic polynomial, we have a result of the parabola. This parabola also appears at different points, which represent different cases.
Those cases are specified by Notes of Chapter Polynomials Class One parabola may cut the x-axis and y-axis at two points. When one parabola may cut the x-axis and y-axis at a single point. The parabola may be entirely above the x-axis or completely below the x-axis. One parabola may be completely above the y-axis or completely below the y-axis.
These are the various cases observed in the zero polynomial while plotting graphs are explained with several solved examples by taking different values. In this section, the Notes of Chapter 2 Maths Class 10 explains the questions of a polynomial by reminding the factorization method, which had been learned in the previous class.
In the factorization, the quadratic polynomial has been split into multiple factors, which means writing each term separately. Chapter 2 - Polynomials. Chapter 4 - Quadratic Equations.
