Practice problem
How are the following problems different?
Simplify: 2+x−(3−2x)2 + x - (3 - 2x)2+x−(3−2x)
Simplify: 2+i−(3−2i)2 + i - (3 - 2i)2+i−(3−2i)
For the expression containing xxx, we need to distribute the negative sign
For the expression containing iii, we need to distribute the negative sign
There is no difference
Type a concept, like “slope” or “photosynthesis”.
