Question

what should be added to x-1/x-2 to obtain 2x*2- 4 /x*2-4​

Answer 1

Step-by-step explanation:

According to the problem,

Let A should be added to1+2x−3x

2

to get result,

1+2x−3x

2

+A=x

2

−x−1

A=x

2

−x−1−(1+2x−3x

2

)

A=x

2

−x−1−1−2x+3x

2

A=4x

2

−3x−2

Therefore, 4x

2

−3x−2 added to the equation.

Answer 2

Step-by-step explanation:

Solution

Step 1

Collecting like terms, and putting them together

(+2–2) and (+1/x-1/x) cancels

Step 2

We are now left with 2x/(x)^2–4

We therefore need to simplify our denominator, which is a difference to of two squares . It simplifies to (x-2)(x+2)

Step 3

Check whether there is a common divisor between the denominator and numerator so as to simplify the expression further. In our case, it is not there.

Therefore, the expression (2x)/(x-2)(x+2) is the answer
