gia tri x thoa man (2x-1)\(^3\) =-8 la
1. gia tri cua x thoa man (2x+3)(x+1)2-(2x+3)(2x-3)
2. so nghiem cua da thuc x3+6x2+11x+6 la ?
3. bieu thuc C = 8-5x-2x2 dat gia tri lon nhat tai x = ?
gia tri x<0 thoa man gia tri tuyet doi cua 2x - 1 = 3mu 2 la x=....
Giúp mình (violympic lớp 8 vòng 7)
goi x0 la gia tri cua x thoa man (3x^3+x^2-13x+5)/(x^2+2x-1)=0 khi do 3x0=
GIA TRI X THOA MAN
(2X-1)^3=8
giup to 3 bai nay
1. gia tri cua x thoa man (2x+3)(x+1)2-(2x+3)(2x-3)
2. so nghiem cua da thuc x3+6x2+11x+6 la ?
3. bieu thuc C = 8-5x-2x2 dat gia tri lon nhat tai x = ?
giup to 3 bai nay
1. gia tri cua x thoa man (2x+3)(x+1)2-(2x+3)(2x-3)

gia tri cua x thoa man
(2x-1)^3=-8
(2x-1)^3=-8
=> (2X-1)^3= -2^3
=> 2x-1=-1
=> 2x= 0
=> x=0
1.gia tri x<0 thoa man (2x-3)2=(x+5)2
2.tap hop cac gia tri cua x thoa man x4-2x3+10x2-20x=0 la S(....)
3.phan tich da thuc xy-12+3x-4 ta duoc (x+a)(y+b) khi do a+b=?
1. so x>0 thoa man \(\frac{5}{x}=\frac{x+1}{22}\)
2. GTLN cua x thoa man \(5^{\left(x-2\right)\left(x+3\right)}\)
3. Gia tri x<0 thoa man /\(x^2+50\)/=/\(-2x^2\)-1/
4. Gia tri nguyen cua x thoa man \(\left(3x-4\right)^5\)=\(^{\left(3x-4\right)^7}\)la x=
5. So gia tri cua x thoa man /x-2014/+/x-2015/=0
6. Gia tri cua x de bieu thuc A=\(\frac{x-3+5}{3-x+2}\)dat gia tri lon nhat la x=
