Check all formulas below:

1. A polynomial p(x) in one variable x is an algebraic expression in x of the form p(x) = anxn + an–1xn – 1 + . . . + a2x2 + a1x + a0 , where a0 , a1 , a2 , . . ., an are constants and an ≠ 0.

a0, a1, a2, . . ., an are respectively the coefficients of x0, x, x2 , . . ., xn

2. The highest power of x in a polynomial is called the degree of that polynomial. For example n is called the degree of the above polynomial p(x).

3. A polynomial of degree one is called a linear polynomial.

4. A polynomial of degree two is called a quadratic polynomial.

5. A polynomial of degree three is called a quadratic polynomial.

6. A real number k is called the zero of a polynomial p(x) if p(k) = 0.

7. Geometrically 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

8. Relationship between Zeroes and Coefficients of a Polynomial

If α and β are the zeroes of the quadratic polynomial p(x) = ax2 + bx + c, a ≠ 0 then

If α, β, γ are the zeroes of the cubic polynomial ax3 + bx2 + cx + d, then

9. Division algorithm for polynomials: It states that 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).

Here p(x) is divided , g(x) is divisior, q(x) is quotient and r(x) is remainder.
