Question

ok stuck again...
Find the zeros of f.
F(x)=xe^x+3e^x

Answer 1

Factor out the exponential, then use the zero product property.

Answer 2

\[F(x)=xe ^{x}+3e ^{x}=e ^{x}(x+3)\] The exponential factor is never zero, so the only zero is at x=-3, where the polynomial factor is zero.

Answer 3

oh ok that makes sense.. thank you
