The Quadratic Equation 2×2-3x- 5 = 0
What is a Quadratic Equation?
At the heart of our mathematical odyssey lies the quadratic equation, a polynomial equation of the second degree. Its paramount importance lies in the fact that it boasts the highest power of 2 within its structural makeup. To delve further into this realm, it is imperative to acquaint ourselves with its general form:
Ax² + Bx + C = 0
In the specific context of our equation, 2×2-3x- 5 = 0, we can discern the following constants: A = 2, B = -3, and C = -5. Now, let us embark on a profound journey to unearth the intricacies concealed within this mathematical masterpiece.
Finding the Roots of 2×2-3x- 5 = 0
The primary and pivotal objective when grappling with a quadratic equation is the identification of its roots, often referred to as solutions or zeroes. These elusive values of ‘x’ are the proverbial keys that unlock the door to making the equation a true statement. Our quest now begins to uncover these enigmatic roots, the very essence of our equation’s existence.
Methods for Solving 2x² – 3x – 5 = 0
Method 1: Factoring
One of the classic techniques for solving quadratic equations is the method of factoring. However, as mathematics often reveals, the path to solutions is not always straightforward. In the case of our equation, 2×2-3x- 5 = 0, it does not readily yield to simple binomial factoring. This enigma beckons us to explore alternative approaches that will unlock its secrets.
Method 2: Quadratic Formula
The quintessential and universally embraced method for resolving any quadratic equation is the venerable quadratic formula. This formula, often hailed as the magnum opus of mathematical elegance, takes the following form:
x = (-B ± √(B² – 4AC)) / (2A)
With bated breath, we shall now apply this formula with meticulous precision to our equation. Armed with the knowledge that A = 2, B = -3, and C = -5, we embark on a journey that promises to unveil the hidden treasures within:
x = (3 ± √((-3)² – 4(2)(-5))) / (2(2))
This seemingly complex equation is the gateway to the two elusive values of ‘x’ that constitute the roots of 2×2-3x- 5 = 0. The utilization of this formula epitomizes the elegance of mathematics in the art of problem-solving, a testament to human intellect.
