I've missed quite alot of school because I was sick and when I get back I have a test right away. The only problem is I have a worksheet and no answers, I really would appreciate help! I can't tell if I'm in the right direction or not for this test! Thank you!!
2. (x-1)^2 + (2-x)(x+2)+3=(x+2)^2-x^2+3x-5
I do not know if you are supposed to combine terms or solve for x.
The first problem can be rewritten
3x - 15 -6x -2 + 14
= 5 - 5x + 3x -36 - x
Now combine terms
-3x -3 = -3x -31
This is an impossibility since it leads to -3 = -31.
The original statement cannot be correct.
