Bai 1: Rut gon bieu thuc:
a, (x2+2)2- (x+2).(x-2).(x2+4)
b, (x+1)2-(x-1)2-3.(x+1).(x-1)
Giup minh voi ! THANK YOU !^^
thu gon bieu thuc
(x+1)^3-x(x^2+3)
Bai 1: Rut Gon Bieu Thuc :
a, (x2 - 1)3 - (x4+ x2+1) (x2- 1)
b, (x4 - 3x2+ 9) (x2+3) - (3+x2)3
Bai 5 : Tim GTLN hoac GTNN neu co cua cac bieu thuc
a, A = x2-2x-1
b, B = 4x2+4x+5
c, C = 2x - x2- 4
GIUP MINH VOI CAM ON NHIEU !^^
giúp mình giải bài này
rut gon bieu thuc 12(5^2+1)(5^4+1)(5^8+1)(5^16+1)
thanks
Bai 1: Rut gon bieu thuc
a, ( m+n )2 - ( m-n )2 + ( m+n ) ( m-n)
b, ( a+b)3 + ( a-b )3 - 2a3
c, ( 2x+1)2 + 2(4x2 - 1) + ( 2x-1 )2
d, ( a+b+c )2 - 2(a+b+c) (b+c ) + ( b+c )2
Rut gon
(x+y+z)-2(x+y+z)×(x+y)+(x+y)
rut gon A=(2x-2)^2-4x(x-2)+46
thu gon bieu thuc
2x(1-x)+2x^2
6) binh viet:x2-12x+36=(x-6)2
Minh viet: x2-12x+36=(6-x)2
Huog neu nha xet minh viet sai , binh viet dung
Son noi:qua vi du minh rut ra hang dang thuc rat dep
Hay neu y kien cua em.Son da rut ra hang dang thuc nao ?
