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

Question

anonymous · Answer

someone please answer this thanx

anonymous · Answer

suppose x2 = a
then your equation is -a-2x-4+2+2x=x+a

anonymous · Answer

that is - in the above equation, not =

anonymous · Answer

ugh... I mean can someone simplify the equation not add letters and stuff

anonymous · Answer

then first job is to add all the letters isn't it?

anonymous · Answer

nooooooooooooooo

anonymous · Answer

its x-2

anonymous · Answer

anonymous · Answer

great! doing what?

anonymous · Answer

I major in psycology and am gettig a teaching degree

anonymous · Answer

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

anonymous · Answer

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)

anonymous · Answer

-1x-2

anonymous · Answer

no they never when i went to high school, they may now tho

anonymous · Answer

I don't know, I didn't go to high school in the US.

anonymous · Answer

no do you see how i got -x -2 ?

anonymous · Answer

now*

anonymous · Answer

so it is -1x-2?? Makes sense

anonymous · Answer

yes, x = 1x. you don't need to write the '1' explicitly.

anonymous · Answer

OK OK
