Question

Find the sum 6/x-4+3/x+1

Answer 1

\[\frac{6}{x-4}+\frac{3}{x+1}\] add just like numbers
\[\frac{a}{b}+\frac{c}{d}=\frac{ad+bc}{bc}\]

Answer 2

\[\frac{6(x+1)+3(x-4)}{(x-4)(x+1)}\] by direct substitution
then you can clean up the numerator with the distributive property and combine like terms

Answer 3
