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.
You can factor out the greatest common factor, then factor by grouping, and then use the zero-product property to solve. Follow along with this tutorial to see a step-by-step explanation! Factoring by grouping is one way to factor a polynomial.
