Question

solve for u:
3u^2-5u=2

Answer 1

First make it in standard form :
\[3u^2 - 5u - 2 = 0\]
Try to make the factors of this equation...

Will you???

Answer 2

after working it out i got u=2 and u=7/3.... im not sure if this is right?

Answer 3

No, 2 is right but other value of u is not right...

Answer 4

Let me answer this :

Have you done like this:

\[3u^2 - 6u + u - 2 = 0\]
\[3u(u - 2) + 1(u - 2) = 0\]

(u-2)(3u + 1) = 0

Now, Either (u - 2) = 0 or (3u + 1 ) = 0

So, u = 2 or u = -1/3...

Answer 5

ohh, okay, makes more sense

Answer 6

thank you :)
