Question

14x^2-686/4x^2-196
can someone help please

Answer 1

\[\frac{14x^2-686}{4x^2-196}=\frac{7-686}{2-196}=\frac{-679}{-194}\]\[\frac{7}{2}\]

Answer 2

thank you nancy, I think I understand this better now.

Answer 3

Another way to do it is take the GCF, giving you
\[14(x^2-49)\div(4(x^2-49)\]
Since the top and bottom both have a (x^2-49), they can cancel.
This will leave you with 14/4, which simplifies to 7/2 or 3.5

Answer 4

thank you entezflare
