1. 3x^2+60x+3/x+3 << if you say 9/30
2. Times above with (3x+2), below with (x+5)
(2x^2+7x-15)(3x+2)/(9x^2-4)(x+5)
(2x-3)(x+5)(3x+2)/(3x-2)(3x+2)(x+5)
*Cut (3x+2) and (x+5)
Tadaa!
(2x-3)/(3x-2)
x = 3/2 and 2/3

x^2+6x+9/ 30 divided by x+3/10

do you mean (x^2+6x+9)/ 30 divided by (x+3)/10 ?

=> (x + 3)(x +3)/30 divided by (x + 3)/10
=> (x + 3)/3 or x/3 + 1

They don't make any sense.
