ok i just want someone to double check my work please. for some reason i think i have the wrong answer.
(use the binomial theorem to expand and simplify this expression)
ok so i used pascal's triangle ...the pascal triangle in my book stops at the 7th row so i got this for my 8th row 1,8,28,56,70,56,28,8,1
so this is what i got ...Please check my work.
ok i know this looks confusing but if you copy and paste it into online calculator it should put everything into place. Did i do this right???
