Question

plzzzz help


z[8.01, 8.07, 10.01]Which of the following represents x squared minus sixteen all over x squared minus four x in simplified form?

Answer 1

\(a^2-b^2=(a-b)*(a+b)\\\huge \frac{x^2-16}{x^2-4}\)
theyre both in that form

Answer 2

hmm?

Answer 3

the question marks disappear if you refresh but idk what you were doing

Answer 4

anyhow my point was, we can rewrite \(\huge \frac{x^2-16}{x^2-4}\) in \(a^2-b^2\) form
let's start with \(x^2-16\)

Answer 5

\[\frac{ x^2{-16} }{ x^{2}-4x}\]

Answer 6

thats how it looks

Answer 7

oh whatever, no big deal

Answer 8

\(x^2-16=(x)^2-(?)^2\)

what goes in t he question mark?

Answer 9

4?

Answer 10

exactly. so now we have \(a^2-b^2=(a-b)*(a+b)\) and \((x^2-4^2)\)

factorize the numerator

Answer 11

hu?
