Where can I test LaTex without disrupting discussions?

$$x^2-6x-7/2x^2+3x +1$$

 

[Hollysmoke]

$$\frac{x^2-6x-7}{2x^2+3x+1}$$

 

[Hollysmoke]

$$\frac{x^2-6x-7}{2x^2+3x+1} x \frac{x^2-6x-7}{2x^2+3x+1} / \frac{x^2-6x-7}{2x^2+3x+1}$$

 

[Hollysmoke]

$$\frac{x^2-6x-7}{2x^2+3x+1} x \frac{4x^2-16x+15}{2x^2-17x+21} / \frac{4x^2-20x+25}{4x^2-1}$$

 

[Hollysmoke]

$$\frac{(x-7)(x+1)}{(2x+1)(x+1)} x \frac{(2x-5)(2x-3)}{2x-3)(x-7)} x \frac{2x+1)(2x-1)}{(2x-5)(2x+5)}$$

 

[Hollysmoke]

$$\frac{(x-7)(x+1)}{(2x+1)(x+1)} x \frac{(2x-5)(2x-3)}{(2x-3)(x-7)} x \frac{2x+1)(2x-1)}{(2x-5)(2x+5)}$$

 

[Hollysmoke]

$$\frac{(x-7)(x+1)}{(2x+1)(x+1)} x \frac{(2x-5)(2x-3)}{2x-3)(x-7)} x \frac{(2x+1)(2x-1)}{(2x-5)(2x+5)}$$

 

[Hollysmoke]

$$\frac{(x-7)(x+1)}{(2x+1)(x+1)} x \frac{(2x-5)(2x-3)}{(2x-3)(x-7)} x \frac{(2x+1)(2x-1)}{(2x-5)(2x+5)}$$

 

[Hollysmoke]

$$\frac{(2x-1)}{(2x+5)}$$

 

[Hollysmoke]

$$\frac{5}{(x+3)} - \frac{(1)}{x-1}$$

 

[Hollysmoke]

$$\frac{5}{(x+3)} - \frac{1}{x-1}$$

 

[Hollysmoke]

$$\frac{5}{(x+3)} - \frac{(1)}{(x-1)}$$
$$\frac{5(x-1)}{(x+3)(x-1)} - \frac{(x+3))}{(x-1)(x+3)}$$
$$\frac{5(x-1)-(x+3)}{(x+3)(x-1)}$$
$$\frac{5x-5-x-3}{(x+3)(x-1)}$$
$$\frac{4x-8}{(x+3)(x-1)}$$
$$\frac{4(x-2)}{(x+3)(x-1)}$$

 

[NateTG]

$$\frac{x^2-6x-7}{2x^2+3x+1} x \frac{4x^2-16x+15}{2x^2-17x+21} / \frac{4x^2-20x+25}{4x^2-1}$$

Did you mean:
$$\frac{x^2-6x-7}{2x^2+3x+1} \times \frac{\frac{4x^2-16x+15}{2x^2-17x+21}}{\frac{4x^2-20x+25}{4x^2-1}}$$
