OpenStudy (anonymous):

What is an excluded value? I have heard of excluded values for rational expressions like 25x / (3x² + 6x)

OpenStudy (anonymous):

\[5x+10/3x^2 + 6x\]

OpenStudy (anonymous):

ah, we needed this other information factor 3x(x + 2) set equal to zero 3x = 0 x+2 = 0 and solve 0 and -2 are the excluded values
