Question

Create your own radical expression, containing a numerical coefficient and two different variables, which can be simplified. Explain, in complete sentences, how you developed the expression, the process of simplifying it, and provide the final simplified expression.

Answer 1

sqrt(x+y) + 2*sqrt(x+y)

I developed this expression by doing the bare minimum asked by the question.

The expression has two variables and radicals with numerical coefficients of 1 and 2, and it can be simplified, by adding, to:

3*sqrt(x+y)
