Introduction

In this article, we will delve into the world of quadratic equations and explore the process of solving the equation $m^2 = 9m$. This equation is a classic example of a quadratic equation, and understanding how to solve it is crucial for students of mathematics, particularly in algebra and calculus. We will break down the solution step by step, providing a clear and concise explanation of each step.

Understanding the Equation

The given equation is $m^2 = 9m$. This equation is a quadratic equation in the form of $ax^2 + bx + c = 0$, where $a$, $b$, and $c$ are constants. In this case, $a = 1$, $b = -9$, and $c = 0$. The equation can be rewritten as $m^2 - 9m = 0$.

Step 1: Factorizing the Equation

To solve the equation, we can start by factorizing the left-hand side of the equation. We can factor out the common term $m$ from both terms, resulting in $m(m - 9) = 0$. This step is crucial in solving the equation, as it allows us to find the values of $m$ that satisfy the equation.

Step 2: Applying the Zero Product Property

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. In this case, we have $m(m - 9) = 0$. Applying the zero product property, we can set each factor equal to zero and solve for $m$. This gives us two possible solutions: $m = 0$ and $m - 9 = 0$.

Step 3: Solving for $m$

We can now solve for $m$ by setting each factor equal to zero. For the first factor, $m = 0$, we have $m = 0$. For the second factor, $m - 9 = 0$, we can add 9 to both sides of the equation, resulting in $m = 9$.

Conclusion

In conclusion, the solutions to the equation $m^2 = 9m$ are $m = 0$ and $m = 9$. These solutions can be obtained by factorizing the left-hand side of the equation and applying the zero product property. Understanding how to solve quadratic equations is a fundamental skill in mathematics, and this article has provided a clear and concise explanation of the process.

Q4: What is the quadratic formula?

A4: The quadratic formula is a mathematical formula used to solve quadratic equations. It is given by $x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$, where $a$, $b$, and $c$ are constants.

Q5: How do I use the quadratic formula?

A5: To use the quadratic formula, you need to substitute the values of $a$, $b$, and $c$ into the formula and simplify. The formula will give you two possible solutions for the variable.

Q6: What is the difference between a quadratic equation and a linear equation?

A6: A quadratic equation is a polynomial equation of degree two, while a linear equation is a polynomial equation of degree one. Quadratic equations have a highest power of two, while linear equations have a highest power of one.

Q7: Can I solve a quadratic equation by graphing?

A7: Yes, you can solve a quadratic equation by graphing. By graphing the quadratic function, you can find the x-intercepts, which represent the solutions to the equation.

Q8: What is the significance of the discriminant in a quadratic equation?

A8: The discriminant is the expression under the square root in the quadratic formula. It determines the nature of the solutions to the equation. If the discriminant is positive, the equation has two distinct real solutions. If the discriminant is zero, the equation has one real solution. If the discriminant is negative, the equation has no real solutions.

Q9: Can I solve a quadratic equation with complex numbers?

A9: Yes, you can solve a quadratic equation with complex numbers. Complex numbers are numbers that have both real and imaginary parts. In the quadratic formula, the square root of the discriminant can be a complex number, which gives you complex solutions.
