Question

(24÷(18-x))-(24÷(18+x)) = 1 ........ explain how it became this ....... 24(18+x)-24(18-x)=(18-x)(18+x)​

Answer 1

Answer:

Step-by-step explanation:

We took LCM in the first process and then shifted the denominator to the RHS.

24÷18-x    -      24÷18+x =   1

{24(18+x) - 24(18-x)}/(18-x)(18+x) = 1

Thence

24(18+x) - 24(18-x) = (18+x)(18-x)
