giai pt: a) x2+(x2+4)-3x(x2+1)+1=0
cac ban viet buoc giai cho nhe!! minh dang can gap lam !!
Giai bat phuong trinh
(x+1/x+1)*(x+2/x+1)=12/x
Nhanh gium nhe mk can gap rui
Phan tich da thuc sau thanh nhan tu
a, x^2+2*x*y+y^2-x-y-12
b, 4*x^4-32*x^2+1
c, 3*(x^4+x^2+1)-(x^2+x+1)^2
d,6+x^4+y^4
e, a^6+a^4+a*b^2+b^2-b^6
giai ho mk nha , mk dag can gap=> mon nhiu lem a
giai phuong trinh |x-99|^100+|x-100|^101 =1 can gap
Tim x va so tu nhien n, biet:
x2 + 2x + 4n - 2n+1 = -2
giai nhanh giup minh nha, minh dang can gap ! THANHS nhiu!
cho phuong trinh (an x):(m-1)x +m^2 -1=0(1) a,giai phuong trinh (1) voi m=2 b, tim gia tri cua m sao cho phuong trinh (1) nhan x=3 lam nghiem
mk dang can gap .cam on truoc a
tinh nhanh bieu thuc sau
a) x^6-20x^5-20x^4-20x^4-20x^3-20x^2-20x+1992 voi x= 21
b)x^7-26x^6+27x^5-47x^4-77x^3+50x^2+x+1989 tai x = 25
c)4029-2015x+2015x^2-....+2015x^2014-x^2015 tai x= 2014
d)A= (x-1/x-2015+x-2/x-2014+x-3/x-2013+....+x-2014/x-2+x-2015/x-1):(1/2 +1/3+1/4+....+1/2016) tai x=2016 dau / o day la phan do nha!!
xin nho cac ban giai giup cho minh! cam on nhieu!!!!!!!! minh dang can ket qua gap
Giai phương trình
a)x(x-1)(x+1)(x+2)=0
b)(x-1?)^4+(x-2)^4=0
giai phuong trinh
x+1/x^2+x+1 - x-1/x^2-x+1 = 3/x(x^4+x^2+1)
