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.
Take the equation 7x = 0. Based on the zero product property, either 7 = 0 or x = 0. It is known that 7 cannot equal zero, therefore, x must equal zero. Now look at the equation xyz = 0. Even though there are three variables, you can separate the expression on the left side of the equation into two expressions.
