2(x-3) 2+2(x 2-1)=4x+1 yields: 4x 2-16x+15=0
So δ=16 2-4 4 15=16
From the formula of the quadratic function, we get x=(16+or-16 under the root number) (2 4)= or.

Solution: 2 (x 2-6x+9)+2x 2-2=4x+12x 2-12x+9+2x 2-2=4x+14x 2-16x=-8
x^2-4x=-2
x-2)^2=-2+4
x-2= root number 2
So x= root number 2 2
"It's squared).

2 (x-3) square + 2 (x square -1) = 4x+1
2 (x square - 6x + 9) + 2x square - 2 = 4x + 14x square - 12x + 16 = 4x + 1
4x square - 16x + 16 = 1
4 (x square - 4x + 4) = 1
4 (x-2) square = 1
x-2) square = 1 4
x-2=±1/2
x=,x=

2 (x square - 6x + 9) + 2x square - 2 = 4x + 12x square - 12x + 18 + 2x square - 2 = 4x + 14x square - 12x + 16 = 4x + 1
4x square - 16x + 15 = 0
2x-5)(2x-3)=0
x = 5 2 (five out of two) or 3 2 (three out of two).

Summary. Hello, I'm honored to answer for you, the form of the equation of 2丨x+1丨-丨3x-2丨=4 is as follows: 2(x+1)-3x+2=4 The solution of the equation is as follows:
2(x+1)-3x+2=4 solution: 2x+2-3x+2=4 4-3x=4 so. 3x=4-4=0.
x=0 3=0 and finally x=0
The equation of 2丨x+1丨-丨3x-2丨=4.
Hello, I'm honored to answer for you, such as 2丨x+1丨-丨3x-2丨Luqi = 4 after the equation is simplified as follows: 2(x+1)-3x+2=4 solution equation is as follows: 2(x+1)-3x+2=4 solution:
2x+2-3x+2=4 4-3x=4 so. Sakura 3x=4-4=0. x=0 3=0 and finally x=0
The above is the equation calculation process of 2丨x+1丨-丨3x-2丨=4, you can take a look.

Hello, please ask the question of whether the x after 1 4 is the division of Qi Luzizi, the x around the equation can be approximated, and the equation becomes 5 3 + 1 4x = 0 denominator.
At the same time, multiply by the number of common cause stools.
12, and finally came out with -20 3.
If x is in the denominator, equation 5 3 + 1 4x=0 is multiplied by 12x at the same time, and finally -3 20 is obtained.

Sun sleepy on both sides multiply at the same time to read 6, get.
6x+3=8x+6
6x-8x=6-3

Solution: x-1 4(1-3x 2)-1 3(2-x 4)=2x-1 hail 4+3x tremor leak 8-2 3+x 12=224x-6+9x-16+2x=48
35x=70x=2
-
Multiply both sides, 4x-12=2x-2, subtract 2x from both sides, add 2, get 2x-10=0, get x=5
-
That's not a joke, is it?
Divide by 2 on both sides at the same time
2(x-3)=x-1
2x-6=x-1
x=5 The second type is directly opened.
4x-12=2x-2
4x-12-(2x-2)=0
4x-12-2x+2=0
2x-10=0
2x=10x=5

Deparentheses: 4x-12=2x-2
Shift: 4x-2x=-2+12
Simplification: 2x=10
Solution: x=5
Answer: Let 2x+3=0, x-1=0, solve: x=-3 2, x=1 When x<-3 2, -2x-3+x-1=4x-3, solve: x=-1 5, not in the range of x<-3 2, rounded. >>>More
Multiply both sides of the first equation by 12 at the same time to get 4x-3y=12, and multiply both sides of the second equation by 6 at the same time to get 3x+2y=12, and then solve the system of equations. >>>More
2x+ solution: the shift term merges the same kind of terms, and obtains: -x = -1 2 coefficients 1, and obtains: x = 1 2
a-2)y=(3a-1)x-1
i.e. y=[(3a-1) (a-2)]x-[1 (a-2)] when [(3a-1) (a-2)] 0, that is, the slope is greater than 0, must pass the first quadrant, and when [(3a-1) (a-2)]=0, a=1 3, y=3 5, must pass the first quadrant. >>>More
