Polynomials refer to mathematical expressions comprising variables, alternatively called indeterminates and coefficients. The video “How to solve polynomial equations in a real life situations” by Teacher Cjane (2018) explains the concept of polynomials and provides an example of using such equations in practice. The word “polynomial” consists of two roots, a combination of which can be described as “many terms” (Teacher Cjane, 2018, 00:01:28). Such expressions can include the difference or sum of individual terms. Polynomials are categorized into monomials, binomials, and trinomials, based on the number of terms in them (Teacher Cjane, 2018, 00:02:04). Furthermore, the following types are distinguished in regard to the polynomial’s degree: zero (constant), linear, quadratic, and cubic polynomials. An example of a polynomial equation is 12xy + 34z – 5 = 0 (Teacher Cjane, 2018, 00:01:05). Overall, polynomials are widely used in real-world situations on a daily basis.
The concept of polynomials is utilized in a variety of fields such as mathematics, economics, engineering, construction, farming, meteorology, astronomy, physics, chemistry, data analysis, management, business, healthcare, and science. Teacher Cjane (2018) provides the following real-life examples of using a polynomial: designing a bridge, a rollercoaster, a guitar, or a vase. In the video, a polynomial equation is implemented to find the length of the wire used to support a tree and anchored in the ground (Teacher Cjane, 2018, 00:04:08). Overall, people can implement such expressions to graph curves, conduct a cost analysis, model stock markets, evaluate values, describe projectiles’ trajectories, and keep data records. Polynomials are critical to assessing the relationship between variables, which emphasizes their importance to mathematical operations. Such characteristics make them useful for completing various tasks in numerous areas of human life.
