Reduce the fraction to lowest terms.

Answer 1

\[\frac{x^2-4x+4}{x^2-4}\]
@Hpbbby what do you think we should do? Do you have any ideas?

Answer 2

factor?

Answer 3

Yeah,
the numerator, it's of the form \(a^2-2ab+b^2\) which is the expansion of \((a-b)^2\), Now use this to rewrite the numerator, will you?

Answer 4

x-2^2

Answer 5

Good, now the denominator is of the form
\(a^2-b^2\) which can be rewritten as \((a+b)(a-b)\), use it to simplify the denominator, would you?

Answer 6

(x-2)(x+2)

Answer 7

x-2/x+2

Answer 8

Yeah, that's correct
Good work @Hpbby :D
