(3x2-5x +7) +(x2 +2x -1)
=(3x2 +x2) (-5x + 2x) (7 -1)
=(4x2) (-3x) (7)
Why does (7 -1) =7 and not 6
and what word do I use to raise my 2 tosquare or to the power of
I also thought it was 6 but I use this web sight to taech myself,and 7 was the answer I was given. I know how to use 4x^2, but I would rather use
4x2 meaning 4x times 2 is different than 4x squared by 2. I just wanted to know which font I would use to make a small 2 above the x.
