Geometrical Meaning of Zeroes of Polynomials

A real number k is said to be a zero of a polynomial p(x), if p(k) = 0.

Polynomials can easily be represented graphically.

Zero of polynomial p(x) is x-coordinate of point where graph of p(x) intersects x-axis. Polynomial p(x) intersects the x-axis @ x=2, thus zero of this polynomial is 2.

Linear polynomial ax + b, a ≠ 0, has exactly one zero

E.g. Zero of linear polynomial p(x) = 2x -6 is 3 & thus the graph of this polynomial intersect x axis only once.

Quadratic polynomial ax² + bx +c, has nil, one or two zeroes

E.g. There are no Zeroes of Quadratic polynomial p(x) = x² + 1 & thus the graph of this polynomial doesn’t intersect x axis.

E.g. There is one Zero of Quadratic polynomial p(x) = x² -4x+4, that is 2 & thus the graph of this polynomial intersect x axis once at x=2.

E.g. There are Two Zeros of Quadratic polynomial p(x) = x² – 4, that is +2, -2 & thus the graph of this polynomial intersect x axis at two place, x=2 & x=-2.

Cubic polynomial ax³ + bx² +cx +d, has one, two or three zeroes. There can’t be any cubic polynomial with Nil zeroes.

E.g. There is one Zero of Cubic polynomial p(x) = x³, that is 0 & thus the graph of this polynomial intersect x axis once at x=0.

E.g. There are Two Zeros of Cubic polynomial p(x) = x³ – x², that is 0 & 1, and thus the graph of this polynomial intersect x axis at two place, x=0 & x=1

E.g. There are three Zeroes of Cubic polynomial p(x) = x³ -4x, that is 0,+2 & -2, and thus the graph of this polynomial intersect x axis at three place, x=0, x=+2 & x=-2.

In general, given a polynomial p(x) of degree n, the graph of y = p(x) intersects the x- axis at at most n points. Therefore, a polynomial p(x) of degree n has at most n zeroes.

Also, Any polynomial of odd degree will never have nil zeroes

Always remember, it is very important to study with full concentration during Revision. Here are a few tips for you on how to revise with full focus:

Create a Distraction-Free Environment: Find a quiet and comfortable place to study where you can minimize distractions. Turn off or silence your phone, log out of social media accounts, and inform others around you that you need uninterrupted study time. A dedicated study environment will help you focus better.
Set Specific Goals: Before starting your study session, set clear and achievable goals. Break down your study material into smaller tasks, and plan what you want to accomplish during each session. Having specific goals will give you a sense of direction and purpose, making it easier to concentrate.
Use the Pomodoro Technique: The Pomodoro Technique is a time management method that involves studying in short, focused intervals, typically 25 minutes, followed by a short break of 5 minutes. After completing four sessions, take a longer break of around 15-30 minutes. This technique can improve focus and productivity by providing regular breaks to recharge.
Stay Organized: Keep your study materials, notes, and resources well-organized. Having everything you need at hand will save time and reduce distractions caused by searching for materials. Use color-coded folders or digital tools to maintain a structured study system.
Practice Mindfulness and Meditation: Before you begin studying, take a few minutes to practice mindfulness or meditation. Deep breathing exercises and clearing your mind of distractions can help you approach your study session with a calm and focused mindset.

Remember, studying with full concentration is a skill that takes time and practice to develop. If you find your mind wandering during study sessions, gently bring your focus back to the task at hand and be patient with yourself. With consistent effort, you can improve your ability to concentrate and make the most of your study time.
