Using the Quadratic Formula to Solve 5x + 6x² + 3: What are the Values of x?

To solve the quadratic equation 6x² + 5x + 3 = 0 using the quadratic formula, we start by identifying the coefficients:

  • a = 6
  • b = 5
  • c = 3

The quadratic formula is given by:

x = (-b ± √(b² – 4ac)) / (2a)

First, we need to calculate the discriminant (b² – 4ac):

b² = 5² = 25

4ac = 4 * 6 * 3 = 72

Now, compute the discriminant:

Discriminant = 25 – 72 = -47

Since the discriminant is negative, this means there are no real solutions; instead, we will have complex solutions.

Now we plug the values into the quadratic formula:

x = (–5 ± √(-47)) / (2 * 6)

This simplifies to:

x = (–5 ± i√47) / 12

Thus, the two complex solutions for x are:

  • x₁ = (–5 + i√47) / 12
  • x₂ = (–5 – i√47) / 12

In conclusion, the values of x for the equation 6x² + 5x + 3 = 0 are complex numbers due to the negative discriminant.
