So when Helmholtz recognized that thought moves at a finite rate, faster than a bird but slower than sound, he missed a fundamental difference between the brain and a telegraph. In our heads, speed is not always the most important thing. Sometimes what really matters is timing.
A solution of a quadratic equation is a value of the variable that makes the equation true. Many quadratic equations. can be solved by factoring and using the zero-factor property. The Zero-Factor Property: When the product of two real numbers is 0, at least one of them is 0.
Step 3: Use the zero-factor property to set each factor equal to zero. Step 4: Solve each resulting linear equation. Step 5: Check the results in the original equation. Example 1: (Solving equations by factoring) Solve the following equations and check the answer.
