so i needed help with 2 questions but forget that. after looking online for tutors chats or something i cant seem to find any of them (that are free). so i guess you guys of this find community are my only hope.

 

question: write the quadratic equation that has 5+(and minus) 3√2 as its roots. 

Space Journal #1: So Apparently i  was dropped on the moon like i'm a mars rover, in a matter of hours i have found the transformers on the dark side of the moon. Turns out its not that dark since dem robots are filled with lights, i waved hi to the Russians on the space station, turns out all those stories about space finding humans instead of the other way around is true(soviet Russia joke). They threw me some Heineken beer and I've been sitting staring at the people of this forum and earth since.

(x - (5+3root2))*(x- (5-3root2)) 

FOIL -- first outer inner last 

 

So, (x-5-3root2)*(x-5+3root2)
