In this article, we will delve into the world of cubic equations and explore the solution to the given equation . We will break down the problem into manageable steps, making it easier to understand and solve.
Understanding the Equation
The given equation is a cubic equation, which means it contains a variable raised to the power of 3. The equation is . Our goal is to solve for the value of .
Step 1: Isolate the Cubic Term
To begin solving the equation, we need to isolate the cubic term. We can do this by adding to both sides of the equation.
6 - 4x^3 + 4x^3 = -494 + 4x^3
This simplifies to:
6 = 4x^3 - 494
Step 2: Add 494 to Both Sides
Next, we add 494 to both sides of the equation to get rid of the negative term.
6 + 494 = 4x^3 - 494 + 494
This simplifies to:
500 = 4x^3
Step 3: Divide by 4
Now, we divide both sides of the equation by 4 to isolate the cubic term.
\frac{500}{4} = \frac{4x^3}{4}
This simplifies to:
125 = x^3
Step 4: Take the Cube Root
To find the value of , we need to take the cube root of both sides of the equation.
\sqrt[3]{125} = \sqrt[3]{x^3}
This simplifies to:
5 = x
Conclusion
In this article, we solved the cubic equation by following a step-by-step approach. We isolated the cubic term, added 494 to both sides, divided by 4, and finally took the cube root to find the value of . The final answer is .
What is the Value of ?
To find the value of , we can substitute the value of into the equation.
-4x^3 = -4(125)
