What Exactly Is a Quadratic Equation?
Before we jump into solving 3x2+bx+4, let's talk about what a quadratic equation really is. In simple terms, a quadratic equation is any equation that can be written in the form ax2+bx+c=0, where a, b, and c are constants, and a ≠ 0. These equations are super important in math because they pop up everywhere—from physics to engineering to economics. Think of them as the building blocks of problem-solving in the real world.
Now, what makes quadratic equations so special? Well, they have a unique property: they can have up to two solutions, depending on the values of a, b, and c. This is where things get interesting because finding these solutions requires a bit of creativity and some good old-fashioned algebra.
Breaking Down 3x2+bx+4
Let's take a closer look at our equation: 3x2+bx+4. At first glance, it might seem like just another random equation, but trust me, there's a lot going on here. The coefficient 3 in front of x2 tells us that this is a quadratic equation, and the "+bx+4" part is where the fun begins. The value of b is what we're going to explore, and it plays a crucial role in determining the behavior of the equation.

What Happens When x Equals Three-Halves?
Alright, let's get to the heart of the matter. When x equals three-halves, we're essentially plugging that value into the equation to see what happens. To do this, we substitute x = 3/2 into 3x2+bx+4 and solve for b. Here's how it works:
- Step 1: Replace x with 3/2 in the equation.
- Step 2: Simplify the terms to find the relationship between b and the other constants.
- Step 3: Solve for b to uncover the mystery.
By following these steps, we can determine the exact value of b that makes the equation true when x equals three-halves. Pretty cool, right?
Why Does This Matter?
You might be wondering, "Why does solving this equation matter in the real world?" Great question! Quadratic equations are used in countless applications, from calculating the trajectory of a rocket to designing suspension bridges. Understanding how to solve equations like 3x2+bx+4 gives you the tools to tackle real-life problems that involve curves, motion, and optimization.
For example, imagine you're an engineer designing a roller coaster. You need to calculate the perfect curve for the tracks to ensure a smooth and thrilling ride. Quadratic equations help you do just that. Or maybe you're a financial analyst trying to predict stock market trends. Quadratic models can help you forecast future prices based on historical data. The possibilities are endless!
The Math Behind the Magic
Now, let's dive into the nitty-gritty of solving 3x2+bx+4 when x equals three-halves. Here's how the math works:
Start with the equation: 3x2+bx+4 = 0. Substitute x = 3/2:
3(3/2)2 + b(3/2) + 4 = 0
Simplify each term:
3(9/4) + (3/2)b + 4 = 0
(27/4) + (3/2)b + 4 = 0
Now, solve for b:
(3/2)b = -(27/4) - 4
(3/2)b = -(27/4) - (16/4)
(3/2)b = -(43/4)
b = -(43/4) × (2/3)
b = -(43/6)
And there you have it! The value of b is -(43/6) when x equals three-halves. Who knew math could be so exciting?
Common Mistakes to Avoid
When solving quadratic equations, it's easy to make mistakes if you're not careful. Here are a few common pitfalls to watch out for:
- Forgetting to substitute the correct value of x.
- Misplacing parentheses or forgetting to distribute terms.
- Skipping steps or rushing through the calculations.
Remember, math is all about precision. Take your time, double-check your work, and don't hesitate to ask for help if you get stuck.
