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.
The Zero Product Property says: If (xâ5)(xâ3) = 0 then (xâ5) = 0 or (xâ3) = 0. Now we just solve each of those: For (xâ5) = 0 we get x = 5. For (xâ3) = 0 we get x = 3. And the solutions are: x = 5, or x = 3.
