Tìm a,b để p(x) = x3 +6x2 +4ax + b chia cho (x-1) (x-3) dư 5
Các ban giupminh giai bai toan nay nha.cam on nhieu.
giai gium minh bai toan :x^2+y^2+2xy+4>0
A=(x-1)3-(x+1)3+6(x+1).(x-1)
2x3-5x=0
(x-1).(3x-1)+(1-x).(x+2)=0
giai ho minh bai nay nhe
3 bai ak
giup tui giai bai toan nay voi
tim GTNN cua P= x^2/y^2+y^2/x^2-3(x/y+y/x)+5 (x#0;y#0)
Bai 5
1/ Tim GTNN : A= x^2+3x+2
2/Tim x,y biet:
a/x^2-4x+y^2+2y+5=0
b/2x^2+y^2-2xy+10x+25=0
Giai ho minh bai 1,2,3,4,5 nhe !!! Minh dang len tren dien dan roi day !!!!
Minh can gap !!! Camon may ban tr'c nha
giai chi tiet giup minh may bai nay nha
1 gia tri x>0 thoa man
(2x-3)2=(x+5)2
2 gia tri lon nhat cua -3x2-6x-4
3 tim gia tri cua x+y biet
x-y=2 ; x*y=99 va y <0
4 nghiem cua phuong trinh
(2x-3)2-4x2-297=0
Rut gon phan thuc: (x^(3)-x^(2)-x-2)/(x^(5)-3x^(4)+4x^(3)-5x^(2)+3x-2)
Minh that su da bo tay vs bai tap nay roi! Cac ban hay giup minh nhe! Minh xin cam on!
7(2x-5)-5(7x-2)+2(5x-7) = (x+2)-(x+4) tim x nhe ai giai giup minh vs
tim x de A thuoc Z biet A=x^2-3x+1/x+1 .Moi nguoi giup minh giai bai nay trong trua nay nha
