Introduction

In mathematics, solving quadratic equations is a fundamental concept that is essential for various fields, including algebra, geometry, and calculus. A quadratic equation is a polynomial equation of degree two, which means the highest power of the variable is two. The general form of a quadratic equation is ${ax^2 + bx + c = 0}$ , where ${a}$ , ${b}$ , and ${c}$ are constants, and ${x}$ is the variable. In this article, we will focus on solving a specific quadratic equation, ${(v+11)(v+1)=0}$ , to find the value of ${v}$ .

Understanding the Equation

The given equation is a quadratic equation in the form of a product of two binomials. To solve for ${v}$ , we need to find the values of ${v}$ that make the equation true. In other words, we need to find the values of ${v}$ that make the product of the two binomials equal to zero.

Factoring the Equation

To solve the equation, we can start by factoring the left-hand side of the equation. Factoring involves expressing the product of two or more expressions as a single expression. In this case, we can factor the equation as follows:

${(v+11)(v+1)=0}$

This can be rewritten as:

${v+11=0 \quad \text{or} \quad v+1=0}$

Solving for ${v}$

Now that we have factored the equation, we can solve for ${v}$ by setting each factor equal to zero and solving for ${v}$ .

Solving ${v+11=0}$

To solve the equation ${v+11=0}$ , we can subtract 11 from both sides of the equation. This gives us:

${v+11-11=0-11}$

Simplifying the equation, we get:

${v=-11}$

Solving ${v+1=0}$

To solve the equation ${v+1=0}$ , we can subtract 1 from both sides of the equation. This gives us:

${v+1-1=0-1}$

Simplifying the equation, we get:

${v=-1}$

Conclusion

In this article, we have solved the quadratic equation ${(v+11)(v+1)=0}$ to find the value of ${v}$ . By factoring the equation and setting each factor equal to zero, we found that the solutions to the equation are ${v=-11}$ and ${v=-1}$ . These values of ${v}$ make the equation true, and they are the only values of ${v}$ that satisfy the equation.
