I have a problem. It says to simplify: t2/t+4 x 4t+16/2t^28

(t2)/(t+4) x (4t+16)/(2t^28)
= (t2)/(t+4) x 4(t+4)/[2(t^24)]
= (t2) x 2/[t+2)(t2)]
= 2/(t+2)
It is important to show parentheses and brackets in problems like this! Otherseise the order of mathematical operations is unclear, and you can get different answers.
