Introduction

The zero product property is a fundamental concept in algebra that states if the product of two or more factors is equal to zero, then at least one of the factors must be equal to zero. This property is used to solve equations that involve products of variables or expressions. In this article, we will apply the zero product property to solve the quadratic equation 144n281=0144n^2 - 81 = 0.

Understanding the Zero Product Property

The zero product property can be stated as follows:

  • If ab=0ab = 0, then a=0a = 0 or b=0b = 0
  • If a(b+c)=0a(b + c) = 0, then a=0a = 0 or b+c=0b + c = 0
  • If a(bc)=0a(b - c) = 0, then a=0a = 0 or bc=0b - c = 0

This property is used to solve equations that involve products of variables or expressions. By applying the zero product property, we can isolate the variable and solve for its value.

Solving the Quadratic Equation

The given quadratic equation is 144n281=0144n^2 - 81 = 0. To solve this equation, we can start by adding 81 to both sides of the equation:

144n281+81=0+81144n^2 - 81 + 81 = 0 + 81

This simplifies to:

144n2=81144n^2 = 81

Next, we can divide both sides of the equation by 144:

144n2144=81144\frac{144n^2}{144} = \frac{81}{144}

This simplifies to:

n2=916n^2 = \frac{9}{16}

Applying the Zero Product Property

Now that we have isolated the variable n2n^2, we can apply the zero product property to solve for nn. We can rewrite the equation as:

n2916=0n^2 - \frac{9}{16} = 0

This can be factored as:

(n34)(n+34)=0(n - \frac{3}{4})(n + \frac{3}{4}) = 0

Solving for nn

Using the zero product property, we can set each factor equal to zero and solve for nn:

n34=0orn+34=0n - \frac{3}{4} = 0 \quad \text{or} \quad n + \frac{3}{4} = 0

Solving for nn in the first equation, we get:

n=34n = \frac{3}{4}

Solving for nn in the second equation, we get:

n=34n = -\frac{3}{4}

Conclusion

In this article, we applied the zero product property to solve the quadratic equation 144n281=0144n^2 - 81 = 0. We started by adding 81 to both sides of the equation and then divided both sides by 144. We then isolated the variable n2n^2 and applied the zero product property to solve for nn. We found two possible solutions for nn: n=34n = \frac{3}{4} and n=34n = -\frac{3}{4}.
