How do you simplify and find the excluded values of #7/(x+3)#?

Answer 1

#x!=-3#

#7/(x+3)" is already in simplest form"#

#"the denominator cannot equal zero as this would make"# #"the expression undefined. Equating the denominator to"# #"zero and solving gives the value that x cannot be"#

#"solve "x+3=0rArrx=-3larrcolor(red)" excluded value"#
