This equation looks complicated as we have to find out the answer for x but when you start solving it, you will find it is the easiest one out there.
Let’s read the below article where you can find step-by-step
instructions to solve it. So, look below:
Know what are quadratic equations?
Let us tell you that quadratic equations are second-degree
polynomial equations. It means it contains the variables raised by the two
powers. Simply put, the quadratic equation is mainly written like this 4x ^ 2 -
5x - 12=0 format where you can find a, b, and c as coefficients. Here, you need
to find the solution to the x variable by solving this equation.
Characteristics of the 4x ^ 2 - 5x - 12=0 quadratic equation
If you see on this quadratic equation, you may find it
difficult. Let’s check what it is actually. This equation showcases some
characteristics fundamental to the solution and even study. It is made of a
parabolic shape and a vertex which represent the minimum and maximum points. If
you understand these characteristics, it helps you enhance your practical

Methods to solve quadratic equation: 4x ^ 2 - 5x - 12=0
Let’s check out different methods to solve 4x ^ 2 - 5x - 12=0
quadratic equation in the below segment:
Factoring method:
In this factoring method, there are two factors to solve this
quadratic equation. To solve it, you need to discover binomials. With the help
of these binomials, you can provide the quadratic equation by multiplying them
together. Now, you will receive a certain equation, i.e., (2X+3)(2X-4)=0. Next, you must make
each equation equal to 0. After this step, you will receive more 2 equations,
such as 2x + 3 = 0 & 2x – 4 = 0. After solving them, you
will get the answer of x and the answer will be x = -3/2 and x = 2.
Quadratic formula:
It is another method to solve the 4x ^ 2 - 5x -
12=0. It is known as the most reliable method. So, let's check it.
We use the quadratic formula that is x = (-b ± √(b^2 – 4ac)) / 2a to
solve 4x ^ 2 - 5x - 12=0. Place the values a = 4, B, and c=12 in this formula
then calculate it. After calculating, you will find x = -3/2 and x = 2 is the
solution for this quadratic equation.
Conclusion:
We have discussed two primary methods to solve the 4x ^ 2 - 5x -
12=0 quadratic equation in this article. You can check both methods in this
article and effectively solve this quadratic equation easily. One more thing
discuss, these methods can be employed by any students due to its simplicity.
