hazestalker: solve(y1=3,y2=4,y3=1,x1=8,x2=3,x3=4,z1=7,z2=1,z3=5, nx = ((y1-y2)*(z1-z3))-((z1-z2)*(y1-y3)), nz = ((x1-x2)*(y1-y3))-((y1-y2)*(x1-x3)), ny = ((z1-z2)*(x1-x3))-((x1-x2)*(z1-z3)),nx,ny,nz)why does not work?

Stu: Thanks Melody, "b) What are rules for + - / * when you've a negative ^ -1 on a fraction bottom? I am not sure what you mean but if the +- is not a part of the index you leave it alone."re: above I meant if we have an exponent of -1 in the below example,eg. we simplify (-a^ -n)/ (b^ -n) = a^ m-n : to solve does m - -n ever become a +? I think that you mean-a-n / a-n => -a-n--n => -a-n+n => -a0 => -1which was obvious really because the same thing was on the top and the bottom.like -2/2 = -1 because the 2s cancelled out.I just did this for someone else, maybe it will also help 140206 neg indices with fractions.JPG When does an odd amount of - and + exponents simplify an answer as - overall and an even amount of - and + or - and - simplify to +.Does it apply to exponents or just applied to signs of coefficients and pronumerals? What about in division (top over bottom)?I don't know, you are making my head spin. (Sorry, I've been at this all day, I am not criticizing your efforts to absorb knowlege) All the normal rules for minus signs apply. Are you sure you know them all.Thanks.

Warped Tour Girl: Can you explain the grouping method of factoring. Can you describe a scenario when the grouping method would be preferred over other methods and show me an equation in this situation?I need help with this, if you can please help(:
