X^2+8x+12 (x )(x ) We know x has to appear twice Then we say what two numbers multiplied together gets you 12 and when added together gets you 8 We know thats 2 and 6 (x 2)(x 6) And since they are both positive... (x+2)(x+6)
(3^x-2)/9^x=1/3^x-2/9^x which converges by thereom it converges to 10/72=5/36 id show work if i could but take my word, if u cant solve it try working out a few partial sums
