Give them something harder.

Correct. I would have used this,trial and error with factors of 120
Obtain x =2
graph is symmertical about x=-2.5
Therefore the other solution is x=-5
Oh ok. Didn't notice thatCorrect. I would have used this,
Let
Now,
Therefore for x to have real solutions,
![]()
let y = x4
New question:
differentiate x
