2x 3 x 1 1 Find the value of x?

The original inequality is shifted to obtain:

2x-3）/(x-1） -1<0

The left side of the above equation is divided into:

2x-3 -x+1)/(x-1)<0

i.e. (x-2) (x-1) <0

Solution:1

If x-1 0

Rule. 2x-3＞x-1

x 2 cannot be x 1 at the same time, x 2, if x-1 02x-3 x-1

x 2 is 2> x >1

Hello: 2x-3) (x-1)<1

2x-32x-x<3-1

x<2 If you don't understand anything about this question, you can ask it, and if you are satisfied, remember.

Good luck with your studies!

Factorization, multiplication with crosses.

Decompose the quadratic term coefficient 3 into 1 3

Decompose the constant term -1 into (-1) 1

Cross multiplication and then add, 1 1 + (-1) 3 = -2, exactly one term coefficient.

So, 3x -2x-1 = (x-1) (3x+1).

This equation can't be calculated, turn it into an equation and try it:

3x²－2x－1=0

Cross multiplication:

x-1)(3x+1)=0

x-1)=0

x=13x+1)=0

3x=-1x=-1/3

x=1；x=-1 3 is the solution of the original equation.

Multiply the crosses to get (3x 1) (x-1).

Here's how, please refer to it: Roll Qing Town.

If it helps, please be sleepy.

The method is as follows, please comma circle for reference:

If there is help from the landslide, please celebrate.

Both sides are squared at the same time. x+1/x+2=9。Get x+1 x=7. The two sides are multiplied by x. The normal answer is to win the auspicious belt.

Since the limit is quietly a continuous divine return function in the number of the limit.

limx→0(3x²-2x+1)

1 [Substitute x=0 directly into the equation to get 1].
