Smart  Math in Roots of Quadratic be Easy with Table Key will lead and guide you to understand how to attract the square root of the result properly, just two steps you already know the outcome of the roots of that number. Well let's continue by reading and observing the steps how to use the square root table.

Before on the subject of the Roots of Quadratic we consider two key below, the red table to find the results in front of numbers after we closed two numbers from the back while the blue to find the results of the last numbers.

The Key Roots of Quadratic 

This table square root note of red table to determine the numbers in front after closing two numbers whereas the blue table to determine the next number or numbers the results back.

Now we will find the square root use by using above key of Roots of Quadratic closed two numbers from the back, which in looking further we see number 1 red table 1 until 3 the key is 1.
