4x + 2 is a polynomial equation in the variable x of degree 1 2. Students can learn about the division algorithm for polynomials of integers and also whether the zeros of quadratic polynomials are related to … A polynomial with a single term of … – 2x, which is the product of constant ‘2’ and the variable ‘x’ For example, consider the polynomial 2x2−5x+3, The middle term in the polynomial 2x2−5x+3 is -5x. But what is the significance of these zeros of a polynomial? Monomial, Binomial and Trinomial are the types. For a polynomial in one variable – the highest exponent on the variable in a polynomial is the degree of the polynomial. It cuts the X-axis at exactly one point. For example, 2x3+5x2+9x+15 is a cubic polynomial. Quadratic polynomials can be factorized by splitting the middle term. Any equation can be represented as a graph on the Cartesian plane, where each point on the graph represents the x and y coordinates of the point that satisfies the equation. In general, a polynomial of degree n has at most n zeros.
