Introduction

In algebra, solving for xx in an equation is a fundamental concept that helps us find the value of the variable. When we have a quadratic equation or a product of two binomials equal to zero, we can use various techniques to find the solutions. In this article, we will explore how to solve for xx in the equation (5x+6)(3x6)=0(5x + 6)(3x - 6) = 0.

Understanding the Equation

The given equation is a product of two binomials, which can be expanded using the distributive property. However, since we are given that the product is equal to zero, we can use the zero-product property to find the solutions. The zero-product property states that if the product of two or more factors is equal to zero, then at least one of the factors must be equal to zero.

Applying the Zero-Product Property

Using the zero-product property, we can set each factor equal to zero and solve for xx. This gives us two separate equations:

  1. 5x+6=05x + 6 = 0
  2. 3x6=03x - 6 = 0

Solving the First Equation

To solve the first equation, we can isolate the variable xx by subtracting 6 from both sides and then dividing by 5.

5x+6=05x + 6 = 0

Subtracting 6 from both sides:

5x=65x = -6

Dividing by 5:

x=65x = \frac{-6}{5}

Solving the Second Equation

To solve the second equation, we can isolate the variable xx by adding 6 to both sides and then dividing by 3.

3x6=03x - 6 = 0

Adding 6 to both sides:

3x=63x = 6

Dividing by 3:

x=2x = 2

Conclusion

In conclusion, we have solved the equation (5x+6)(3x6)=0(5x + 6)(3x - 6) = 0 using the zero-product property. We found that the solutions are x=65x = \frac{-6}{5} and x=2x = 2. These values satisfy the original equation, and we can verify this by plugging them back into the equation.

Final Answer

The final answer is:

C. x=65x = \frac{-6}{5} or x=2x = 2
