Question

For all r≠±2, r2−5r+6 (line in the middle
r2−4 = ?

Answer 1

rational expressions

Answer 2

are we just simplifying?

Answer 3

yes just simplifying

Answer 4

okay then we first factor the numberator

Answer 5

numerator*

Answer 6

r^2-5r+6=(r-2)(r-3)

Answer 7

The bottom factors as a difference of square: r^2-4=(r-2)(r+2)

Answer 8

oh no i'm sorry we're solving for r≠±2

Answer 9

okay thats fine, still follow the steps i have showed you

Answer 10

So, now we have :
(r-2)(r-3)
--------
(r-2)(r+2)

Answer 11

now, we diivde out (r-2)

Answer 12

and we are left with out solution:
(r-3)
----
(r+2)

Answer 13

are we good?

Answer 14

no I haven't taken math in so long, i'm so lost, can you possibly type it in one text step by step if possible
