Vẫn là câu tìm x nha các bạn iu quý : x^3+3x^2+3x=0
Mong là các bạn giúp đc mình ạ
Mơn nhìu nhìu nhìu nhìu nha
I lớp diu chu cà mooooooooooooooo
Ta có : \(x^3+3x^2+3x=0\)
\(\Leftrightarrow x.\left(x^2+3x+3\right)=0\)
\(\Leftrightarrow\orbr{\begin{cases}x=0\\x^2+3x+3=0\end{cases}\Leftrightarrow}x=0\)
x3 + 3x2 + 3x = 0
<=> x( x2 + 3x + 3 ) = 0
<=> \(\orbr{\begin{cases}x=0\\x^2+3x+3=0\left(1\right)\end{cases}}\)
Ta có (1) = x2 + 3x + 3
= ( x2 + 3x + 9/4 ) + 3/4
= ( x + 3/2 )2 + 3/4 ≥ 3/4 > 0 ∀ x
=> (1) vô nghiệm
Vậy phương trình có nghiệm duy nhất là x = 0
Bài làm :
Ta có :
\(x^3+3x^2+3x=0\)
\(\Leftrightarrow x\left(x^2+3x+3\right)=0\)
\(\Leftrightarrow\orbr{\begin{cases}x=0\\x^2+3x+3=0\end{cases}}\)
\(\Leftrightarrow\orbr{\begin{cases}x=0\\\left(x^2+2.\frac{3}{2}x+\frac{9}{4}\right)+\frac{3}{4}=0\end{cases}}\)
\(\Leftrightarrow\orbr{\begin{cases}x=0\\\left(x+\frac{3}{2}\right)^2=\frac{-3}{4}\end{cases}}\)
\(\text{Vì }:\left(x+\frac{3}{2}\right)^2\ge0\)
\(\Rightarrow\text{Không tồn tại x để : }\left(x+\frac{3}{2}\right)^2=\frac{-3}{4}\)
Vậy x=0
Chúc bạn học tốt !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

4-(27-3)=x-(13-4)
các bạn giúp mình nhanh nha,mơn nhìu!!!
=> 4-24 = x-9
=> x-9 = -20
=> x = -20 + 9 = -11
Vậy x = -11

Tìm các cặp số nguyên x,y sao cho x-y+2xy =3
GIÚP MÌNH NHA. MÌNH CẦN GẤP LẮM. CẢM MƠN CÁC BẠN RẤT NHÌU
ta có x-y+2xy=3<=>2x-2y+4xy=6<=>2x(2y+1)-(2y+1)=5<=>(2x-1)(2y+1)=7
Vì (2x-1)(2y+1)=7 => \(2x-1\inƯ\left(7\right)\)={1,-1,7,-7}{}
=>\(x\in\){1,0,4,-3}=> y\(\in\){3,-4,0,-1}

Ta có:
x - y + 2xy = 3
Suy ra 2x - 2y + 4xy = 6
Suy ra 2x( 2y + 1 ) - ( 2y + 1 ) = 5
Suy ra ( 2x - 1 ) ( 2y + 1 ) = 7
Vì ( 2x - 1 ) ( 2y + 1 ) = 7
Suy ra 2x -1 thuộc Ư (7) = { 1 ; -1 ; 7 ; -7 }
Suy ra x thuộc { 1 ; 0 ; 4 ; -3 }
y thuộc { 3 ; -4 ; 0 ; -1 }
