Basic Concepts
• Zeroes of a polynomial. k is said to be zero of a polynomial p(x) if p(k) = 0• Graph of polynomial. (i) Graph of a linear polynomial ax + b is a straight line. (ii) Graph of a quadratic polynomial p(x) = ax2 + bx + c is a parabola open upwards like ∪, if a > 0. (iii) Graph of a quadratic polynomial p(x) = ax2 + bx + c is a parabola open downwards like ∩, if a > 0. (iv) In general a polynomial p(x) of degree n crosses the x-axis…
