2x-3 / X when x is taken, the fraction is meaningless

2x-3 / X when x is taken, the fraction is meaningless

x/(2x-3)
When the denominator is 0, the score is meaningless
2x-3=0
x=3/2
That is: when x is 3 / 2, the denominator is meaningless!

When x takes what value, the fraction [x ^ 2-9] / [(x + 2) (2-3)] 1. Meaningful 2. Meaningless 3. The value is zero

When the denominator (x + 2) (2 -- 3) is not equal to 0, i.e., X is not equal to - 2, it is meaningful
2. When the denominator (x + 2) (2 -- 3) is equal to 0, that is, when x is equal to - 2, it is meaningless
3. When the denominator (x + 2) (2 -- 3) is not equal to 0 and the numerator (x ^ 2 -- 9) is equal to 0, that is, when x is equal to plus or minus 3, the value is zero

The following fraction makes sense when x is taken as (1) the quadratic power of X + 2x + 3 / 2-x (2) 1 + 1 / X thank you

(1)R
(2)x≠-1

When x is taken, the following fraction is meaningless? (1) x + 2x (2) x squared - 1 (3) x squared + 2x X

∵ (1) x + 2x of 1 is meaningless
∴x+1=0
∴X=-1
When x = - 1, 2x of X + 1 is meaningless
(2) ∵ the square of X-1 / 4 is meaningless
The square of x-4 = 0
∴X=±2
When x = ± 2, the square of X-1 / 4 is meaningless
(3) ∵ the square of X + 2x parts x is meaningless
The square of X + 2x = 0
ν x = 0 or x = - 2
When x = 0 or x = - 2, the square of X + 2xth of X is meaningless

Make fraction 2x + 1 The value of 2x − 1 meaningless x is______ .

∵ fraction 2x + 1
2x − 1 is meaningless,
∴2x-1=0，
∴x=1
2．
So the answer is: 1
2．

When x is taken, the following fractions are meaningless? (1) 2x-3 parts x (2) 5x + 10 parts X-1 online, etc., speed and high quality

(1) 2x-3 parts x x = 3 / 2
(2) 5x + 10thx-1 x = - 2
Zero denominator is meaningless

2. What is the value of X, the following fraction is meaningless? (1) 2x-3 parts x (2) 5x + 10 parts X-1

(1) 2x-3 / X
2x-3=0
2x=3
x=3/2
(2) 5x + 10thx-1
5x+10=0
x=-5/2

In order to make 2x of fraction x-3 meaningful, the condition that x must satisfy is

Denominator x-3 ≠ 0
So x ≠ 3

The least common denominator ()

The square of fraction 2x is X-1, 3x is 4, 4x is the simplest common denominator (12x 3)

Fraction x square - 4Y square / x square + 4x + 4 times x + 2 / 3x square + 6xy

(x²-4y²)/(x²+4x+4)×（x+2)/(3x²+6xy)
=[（x+2y）(x-2y)]/(x+2)²×(x+2)/[3x(x+2)]
=（x-2y）/[3x(x+2)]
=(x-2y）/(3x²+6x)
