Answer 1

Alot tougher huh :)

Answer 2

\[\Large\frac{x^2-9}{x^2+2x}\cdot\frac{x+2}{x-3}\]
Why can't you just put parentheses lol

Answer 3

ok factorize \(x^2-9\) first by using \(a^2-b^2=(a-b)(a+b)\) :)

Answer 4

Then factorize \(x^2+2x\) by taking out the common factor :)

Answer 5

Oh the perfect square formula

Answer 6

oh you call it the perfect square formula? interesting name :p

Answer 7

(x+3)(x-3)

Answer 8

right

Answer 9

then factorize \(x^2+2x\) by taking out the common factor :)

Answer 10

x(x+2)

Answer 11

ahhhh

Answer 12

now they cancel!

Answer 13

yep :D
So now we got \(\dfrac{(x+3)(x-3)}{x(x+2)}\cdot\dfrac{x+2}{x-3}\)

Answer 14

yep they cancel :D
