Question

Can anybody solve 9x^4+26x^3=3?

Answer 1

Mmmm.. something's wrong. Here is Wolfram's solution:

Answer 2

How about this?

Factorise x^3(9x+26) = 3

3 can only be 3 times 1, or 1 times 3, so

x^3 = 3 or 1, and 9x+26 = 1 or 3

Answer 3

3 can be 6 times 1/2 as well as many others (including complex values) I suspect there are several values for x

Answer 4

Attached is the symbolic solution for the two real equation roots.
I cannot imagine that this equation would be presented as home work.

Answer 5

Geez!, I hope ema123 good luck with it!
