Understanding Quadratic Equations 4x ^ 2 – 5x – 12 = 0
Quadratic equations, a fundamental concept in algebra, have intrigued mathematicians and learners alike. They are polynomial equations of the second degree, involving a variable raised to the power of two (x^2). These equations commonly take the form of ax^2 + bx + c = 0, where a, b, and c are constants. Quadratic equations play a crucial role in diverse mathematical applications, including physics, engineering, and finance.
The Given Equation 4x ^ 2 – 5x – 12 = 0
Our focus equation, 4x ^ 2 – 5x – 12 = 0, is a specific example of a quadratic equation. It features coefficients a = 4, b = -5, and c = -12. The objective is to discover the values of x that satisfy this equation and decipher its implications.
Factoring the Equation 4x ^ 2 – 5x – 12 = 0
One of the fundamental methods to solve quadratic equations is through factoring. The process involves finding two numbers that, when multiplied, yield the product of a and c (ac) and when added, give the coefficient b. For our equation, ac = 4 * -12 = -48, and we must find two numbers that sum up to -5. These numbers turn out to be -8 and 3. Consequently, we rewrite the equation as (4x + 3)(x – 4) = 0, a crucial step toward unraveling its solution.
Zero Product Property
The zero product property is a key principle in algebra, asserting that if the product of two factors is zero, at least one of the factors must be zero. This principle aids us in generating two possible equations from the factored form: 4x + 3 = 0 and x – 4 = 0. These equations offer insights into the potential solutions of our original equation.
Solving for x
With the foundation laid, we proceed to solve the derived equations. Solving 4x + 3 = 0, we find x = -3/4. Similarly, solving x – 4 = 0 yields the solution x = 4. These solutions provide the values of x that render the equation 4x ^ 2 – 5x – 12 = 0 valid.
Solutions of the Quadratic Equation 4x ^ 2 – 5x – 12 = 0
The culmination of our efforts reveals the solutions of the quadratic equation 4x ^ 2 – 5x – 12 = 0 as x = -3/4 and x = 4. These values hold the key to the equation’s essence, as they satisfy its mathematical requirements.
Quadratic Formula
An alternative and robust approach to solving quadratic equations is the quadratic formula: x = (-b ± √(b^2 – 4ac)) / 2a. Applying this formula to our equation leads to the same solutions we obtained earlier: x = -3/4 and x = 4. This formula provides a versatile tool for solving various quadratic equations.
Graphical Representation
Visualizing equations can provide profound insights. Graphing the quadratic equation 4x ^ 2 – 5x – 12 = 0 results in a distinctive parabolic curve. The points where this curve intersects the x-axis correspond to the solutions of the equation. In our case, these points coincide with x = -3/4 and x = 4.
