When x=______ Fraction 2x + 1 3x − 4 is meaningless

When x=______ Fraction 2x + 1 3x − 4 is meaningless

If the fraction is meaningless, then 3x-4 = 0,
∴x=4

When x=______ The fraction 3x / 2x-1 is meaningless

When x=__ One in two____ The fraction 3x / 2x-1 is meaningless

Firstly, the fraction (x-1 minus x + 1 / X-2) is divided by the square of X + 2x + 2x of 2x-x, and then an appropriate number is selected as the value of X to be substituted into the job search

(x-1 minus x + 1 X-2) divided by the square of X + 2x + 2x of 2x - x = [(x-1) / X - (X-2) / (x + 1)] × (x + 1) 2 / X (2x-1) = [(x-1) (x + 1) - x (X-2)] / X (x + 1) × (x + 1) 2 / X (2x-1) = (x-1-x 2 + 2x) / X (2x-1) = (2x-1) / x ^ (...)

When x is the value, the fraction 2x-3 divided by the square of 1 + X: (1) is a positive number; (2) is a negative number; (3) is zero

(2x-3)/(1+x)>0
x> 3 / 2 or x < - 1
(2x-3)/(1+x)<0
-1(2x-3)/(1+x)=0
x=3/2

If fraction a divided by 1 minus x minus B divided by x minus 2 = x minus 3 divided by the square of x minus 3x + 2, find the values of a and B Calculation process, no answer

(x-3)/(x^2-3x+2)
=(x-3)/(x-1)(x-2)
=2/(x-1)-1/(x-2)
=-2/(1-x)-1/(x-2)
So, a = - 2, B = 1

When x=______ When, |x| - 1 The value of x2 + 2x-3 is zero

∵|x|-1
The value of x2 + 2x-3 is zero,
Qi
|x|-1=0
x2+2x-3≠0 ，
X = - 1
So the answer is: - 1

Mathematical fractional equation: 5 divided by the square of x plus x minus 1 divided by the square of x minus x equals 0

5/(x²+x)-1/(x²-x)=0
5/x(x+1)-1/x(x-1)=0
5x-5-x-1=0
4x=6
x=3/2
X = 3 / 2

The fraction 1 + X / 2x-5 is meaningless when x is more than or equal to 1

(1) The fraction is meaningless and the denominator is 0
So 2x-5 = 0, x = 5 / 2
When x = 2.5, the fraction is meaningless
(2) Equal numerator and denominator, fraction value = 1
1+X=2X-5
X=6
When x = 6, the fractional value is 1

When x = - 2, X-B of fraction 2x + A is meaningless; when x = - 4, fraction value is zero, then what is a + B = what?

A=4
b=-4
So it's 0
