The roots of a mathematical expression

Yahely Levy
Posted 20 hours ago

Hello everyone,

I entered the following algebraic expression in the Wolfram|Alpha's search engine: enter image description here

It gave me the following values as the roots of the expression: enter image description here enter image description here

What do these "roots" mean? I've seen in step-by-step solutions that the roots are obtained when when the expression equals zero. Is this true for this example as well?

Thanks in advance,

Yahely

Yes, roots are obtained by setting the expression equal to zero. When you have many variables, there are usually several ways to express all the possible roots. W|A is showing one of them in the first "pod" (four lines; not sure why the 4th line gets an extra "Root" header).
