Question 8599: I am having the hardest time with this one. When I try to plug in x it does not work for this equation. Some one please let me know what I am doing wrong.
Here is how I got my answer and everything.
5x -(2x + 1) = 2 - 3(x + 2)
5x - 2x - 1 = 2 - 3x - 6
3x - 1= -3x -4
3x + 3x = -4 + 1
6x = -3
x = -3/6
x = -1/2
Is this right? Where did I go wrong?

Question 8891: Respected sir,
Factorize x^4-1
I have solved it like this:
(x^2)2-(1)^2 (Formula a^2-b^2= (a+b)(a-b)
(x^2+1)(X^2-1)
But the answer is (x^2+1)(x+1)(x-1)
Sir, my point is if the 2nd term i.e. (x^2-1)is further factorized to (x+1) (x-1), then why not the first term i.e. (x^2+1). Pl. make me understand.
