Can someone simplify this expression for me? -1x2-2x-4+2+2x-1x+1x2? for the 1x2, 2 is an exponent.

suppose x2 = a then your equation is -a-2x-4+2+2x=x+a
anonymous
  • anonymous
that is - in the above equation, not =

ugh... I mean can someone simplify the equation not add letters and stuff
anonymous
  • anonymous
then first job is to add all the letters isn't it?
anonymous

nooooooooooooooo
anonymous

can you describe a situation that 55-7x would be used in

I see, I thought they taught basic algebra in high school. Anyway, -1x2-2x-4+2+2x-1x+1x2 = -x^2 - 2x +4 +2 +2x -x +x^2. Now, you need to bunch up all the like terms together, so -x^2+x^2 -2x +2x -x -4 + 2 = -x -2 (because -x^2+x^2 = 0 and -2x+2x = 0 and -4 +2 = -2)

-1x-2
anonymous
  • anonymous
no they never when i went to high school, they may now tho
anonymous
  • anonymous
I don't know, I didn't go to high school in the US.
anonymous
  • anonymous
no do you see how i got -x -2 ?
anonymous
  • anonymous
now*
anonymous
  • anonymous
so it is -1x-2?? Makes sense
anonymous
  • anonymous
yes, x = 1x. you don't need to write the '1' explicitly.
anonymous
  • anonymous
OK OK
