thanks!!!
Can I take out -2 at the first step? I just integrate x² ?
Take out -2 as if you jump to the third step, no difference.
Still have to put the modulus, coz the substitution of limit is negative.
If you remove the negative sign from -2, then remove the modulus as well. As if you integrate y=2x², the mirror image of the curve, a positive region then...
