Find the value of x: 2x^3 - 5x^2 - x + 20 = 0
would you like to go for a trignometric solution ?
I just need the value of x :o the answers have 2 x values. Its a whole different equation but Ive added everything and I just needed help on finding the x values of this because It confused me
what is the ans.?
if you want soln,,i can provide hint : see shubhamsrg's soln : http://openstudy.com/users/shubhamsrg#/updates/4fed5f8ae4b0bbec5cfcc1ac
first you have to convert the eqn into depressed but..
1: x= -4/3, x= -5 2: x= -4/3, x= 5 3:x= 4/3, x= -5 4:x= 4/3, x= 5
I tried plugging it into wolframalpha already.. didnt work -_-
didn't work! there the ans. given is -1.6
Ok that gives me one answer but :o
I guess ill just try Plugging 5 and negative 5 into the original thing.. Thanks :p
Wait can Someone actually Help me? Cause Ive tried plugging the two 5's in but Its not equaling out. @Wired @JohnHanShanghai , the original equation is this,
|dw:1342092140095:dw|
