$\frac{x^2-9}{3x^2+8x-3}\div \frac{x-3}{x+2}$
You need to use  tags to get TSR to parse .

Also it automatically parses as an equation so you don't need the $s to make it an inline equation. 3. (Original post by ra1500)$\frac{x^2-9}{3x^2+8x-3}\div \frac{x-3}{x+2}$factorise top and both of both fractions then cancel out by cross multiplication 4. Factorise the denominator and cancel another common factor. 5. (X+2)/(3x-1) 6. (X^2 -9)/(3x^2 +8x -3) = (x-3)(x+3)/(3x-1)(x+3) = (x-3)/(3x-1) (X-3)/(3x-1) / (x-3)/(x+2) = (x-3)(3x-1) * (x+2)/(x-3) = (x-3)(x+2)/(3x-1)(x-3) = (x+2)/(3x-1) 7.
