X-1/x-2+x+3/x-4=2/(x-2).(4-x)

Varvara68 [4.7K]

The given equation x-1/x-2+x+3/x-4=2/(x-2).(4-x) is correct. the answer is proved.

According to the statement

we have given that the equation and we have to prove that the given answer is a correct answer for those equivalent equation.

So, The given expression are:

$\frac{x-1}{x-2} +\frac{x+3}{x-4} = \frac{2}{(x-2).(4-x)}$

And we have to prove the answer.

So, For this

$\frac{x-1}{x-2} +\frac{x+3}{x-4}$

$\frac{({x-1}) ({x-4}) +({x+3})({x-2})} {(x-2) (x-4)}$

Then the equation become

$\frac{x^{2} -4x -x +4 + x^{2} -2x + 3x -6 }{(x-2) (x-4)}$

Now solve it then

$2x^{2} - 4x -2 / (x-2) (x-4)$

Now take 2 common from answer then equation become

$\frac{x-1}{x-2} +\frac{x+3}{x-4} = \frac{2}{(x-2).(4-x)}$

Hence proved.

So, The given equation x-1/x-2+x+3/x-4=2/(x-2).(4-x) is correct. the answer is proved.

Chin made an error in his chart showing the multiplication of the binomial by the trinomial. Which change can be made to correct

stealth61 [152]

Answer:

The expression 6x should be 6x^2.

Step-by-step explanation:

Given is the chart of multiplication of the binomial by the trinomial.

Let's check each element in the chart:-

3x times x^2 = 3x^3

3x times 2x = 6x^2

3x times 4 = 12x

2 times x^2 = 2x^2

2 times 2x = 4x

2 times 4 = 8

From the given chart, we can identify that <u>6x should be 6x^2.</u>

Hence. option B is correct, i.e. The expression 6x should be 6x^2.
