What is the Meaning of This Quadratic Equation?
The given quadratic equation,4x² – 5x – 12 = 0, represents a second-degree polynomial equation where the highest power of the variable is 2. The equation includes three terms, namely the quadratic term (4x²), the linear term (-5x), and the constant term (-12).
How Can We Find the Roots of This Equation?
To find the roots (or solutions) of this quadratic equation, 4x ^ 2 – 5x – 12 = 0, we can apply the widely-used quadratic formula:
x = (-b ± √(b² – 4ac)) / (2a)
In this formula, a, b, and c represent the coefficients of the quadratic equation. For our given equation, the coefficients are as follows:
a = 4, b = -5, and c = -12.
By substituting these values into the quadratic formula, we can calculate the roots of the equation.
Analyzing the Roots
Root 1: What is the value of x for the positive root?
Using the quadratic formula, we can calculate the value of x for the positive root:
x = (-(-5) + √((-5)² – 4 * 4 * -12)) / (2 * 4)
Simplifying further, we have:
x = (5 + √(25 + 192)) / 8
x = (5 + √217) / 8
Therefore, the positive root of the equation 4x ^ 2 – 5x – 12 = 0 is (5 + √217) / 8.
Root 2: What is the value of x for the negative root?
Similarly, we can calculate the value of x for the negative root:
x = (-(-5) – √((-5)² – 4 * 4 * -12)) / (2 * 4)
Simplifying further, we have:
x = (5 – √(25 + 192)) / 8
x = (5 – √217) / 8
Therefore, the negative root of the equation 4x ^ 2 – 5x – 12 = 0 is (5 – √217) / 8.
Summary
In conclusion, by understanding the process of unlocking the solution to the quadratic equation 4x ^ 2 – 5x – 12 = 0, we can find its roots. The positive root is (5 + √217) / 8, while the negative root is (5 – √217) / 8. Solving quadratic equations not only enhances our mathematical abilities but also equips us with problem-solving skills applicable in various fields. So, the next time you encounter a quadratic equation, don’t be intimidated. Embrace the challenge and unlock its solution!
