Hello. Can someone show me how to 'multiply and express the product in simplest form.' If I can get a detailed example for the first one, I could go my own way for the other two.

1.

x - 3

(_______)^3 . 1

2 (______)^2

x - 3

2.

x^2 - 9

_______ . x^2 - 4

x + 2 _______

x - 3

3.

x^2 + 5x + 4 x + 1

_____________* _______

(x + 3)^2 x^2 - 9

The . is times, and the * is divided by.

Many thanks in advance.

The above formatting is not the way I wanted, so I'll repost

(x - 3/ 2)^3 .(1 / x - 3)^2

x^2 - 9/x + 2 .x^2 - 4/ x - 3

x^2 + 5x+4/(x+3)^2 * x+1/ x^2-9

It helps to use common notation and clarify using parentheses, brackets and use of spaces. "*" = multiply and "/" indicates divide online.

(x - 3/ 2)^3 .(1 / x - 3)^2 = (x - 3/ 2)^3 * (1/x - 3)^2 (?)

x^2 - 9/x + 2 .x^2 - 4/ x - 3 = (x^2 - 9/x + 2) * (x^2 - 4/x - 3) (?)

x^2 + 5x+4/(x+3)^2 * x+1/ x^2-9 = [(x^2 + 5x+4)/(x+3)^2] / (x+1)/(x^2-9) (?)

Can you improve the formatting again?
