The smallest and greatest points are represented by a vertex and a parabolic shape. Gaining an understanding of these traits improves. Your ability to apply practical solutions and insights.

**Quadratic equation solutions: 4x^2 – 5x – 12=0**

In the section below, let’s examine some approaches to solving the quadratic equation 4x^2 – 5x – 12=0:

**Factoring technique**

This quadratic equation can be solved using two factors in the factoring method. You must learn about binomials to solve it. By multiplying these binomials collectively, you may provide the quadratic equation. You will now be presented with the equation **(2X+3)(2X-4)=0.** The next step is to set the value of each equation to 0.

Following this step, you will be given further two equations, **like 2x – 4 = 0 and 2x + 3 = 0. You will obtain the answer of x after solving them, which is x = -3/2 and x = 2.**

**Formula for quadratics**

This is an alternative approach to solving **4x^2 – 5x – 12=0.** It is regarded as the most trustworthy approach. Let’s examine it now. To solve 4x^2 – 5x – 12=0, we apply the quadratic formula, **x = (-b ± √(b^2 – 4ac)) / 2a. Enter a = 4, B, and c = 12 in this formula**, then perform the calculation. Calculating will reveal that the answer to this quadratic equation is **x = -3/2 and x = 2.**

**Completing the Square Method**

For those inclined towards algebraic manipulations, completing the square is another technique to solve “4x^2 – 5x – 12 = 0”. Here is the methodology:

- Recast the equation as
**(x – h)^2 = k.** - Find the value of h by halving the coefficient of x and squaring the result.
- Add and subtract the value of h^2 in the brackets to complete the square.
- Solve for x by taking the square root of both sides and isolating x.

**Parabola, Vertex Finding: Locate the Vertex of y = 4×2-5x-12**

The Vertex is the highest or lowest point on a parabola. As a result of opening up, our parabola has an absolute minimum, or lowest point. Because the coefficient of the first term. 4, is positive (greater than zero), we already knew this before plotting “y”. A vertical line of symmetry travels across the vertex of every parabola. Due to its symmetry, the line of symmetry would, for instance. Cross the middle of the parabola’s two x-intercepts, which are its roots or solutions. That is, assuming there are two actual solutions to the parabola.

Many real-world scenarios, such as the height above the ground of an object. Thrown upward after a certain amount of time, can be modeled using parabolas. We can get information from the parabola’s vertex, such as the highest. Point an object thrown upwards can go. We therefore need to be able to determine the vertex’s coordinates. -B/(2A) gives the x-coordinate of the vertex for any parabola, Ax2+Bx+C. The x coordinate in our instance is 0.6250. We may determine the y-coordinate by plugging the parabola formula, **0.6250, for x: y = 4.0 0.62 0.62 – 5.0 * 0.62 – 12.0 or y = -13.562**

**In summary**

In this post, we have covered the two main approaches to solving the quadratic problem 4x^2 – 5x – 12=0. You may simply answer this quadratic equation . by using the two approaches described in this article. One last thing to talk about is that because these techniques are so basic, any student can use them.
