Are you struggling to find the solutions to **4x^2-5x-12=0**? Look no further! In this solution, we’ll guide you step-by-step through the process of solving the quadratic equation **4x^2 – 5x – 12 = 0** using the **quadratic formula**. Get ready to discover the exact solutions to this equation and impress your math teacher with your newfound skills!

## Solve Using Quadratic Equation

To solve the quadratic equation **4x^2 – 5x – 12 = 0**, you can use the **quadratic formula**:

x = (-b ± √(b^2 – 4ac)) / 2a

where **a = 4**, **b = -5**, and **c = -12**.

Substituting these values into the formula, we get:

x = (-(-5) ± √((-5)^2 – 4(4)(-12))) / 2(4)

Simplifying this expression:

x = (5 ± √(25 + 192)) / 8

x = (5 ± √217) / 8

So the solutions to the equation are:

x = (5 + √217) / 8

or

**x = (5 – √217) / 8**

These are the exact solutions to the equation. If you need decimal approximations, you can use a calculator to evaluate the square root of 217 and simplify the fractions.

## Explanation – 4x^2-5x-12=0

Here’s a step-by-step explanation of how to solve the quadratic equation ** 4x^2 – 5x – 12 = 0** using the quadratic formula:

**Step 1**: Identify the values of a, b, and c in the quadratic equation.

In the equation 4x^2 – 5x – 12 = 0, the coefficient of x^2 is 4, the coefficient of x is -5, and the constant term is -12. So, we have:

a = 4 b = -5 c = -12

**Step 2**: Substitute the values of a, b, and c into the quadratic formula.

The quadratic formula is:

x = (-b ± √(b^2 – 4ac)) / 2a

Substituting the values of a, b, and c, we get:

x = (-(-5) ± √((-5)^2 – 4(4)(-12))) / 2(4)

**Step 3**: Simplify the expression under the square root sign.

Simplifying the expression under the square root sign, we get:

√((-5)^2 – 4(4)(-12)) = √(25 + 192) = √217

**Step 4**: Simplify the expression inside the parentheses.

Simplifying the expression inside the parentheses, we get:

x = (5 ± √217) / 8

These are the exact solutions to the quadratic equation **4x^2 – 5x – 12 = 0**. If you need decimal approximations, you can use a calculator to evaluate the square root of 217 and simplify the fractions.
