In a Chemical formula, Subscript figures tell us how numerous of the element to their upper-left there are in the patch.
What is a chemical formula?
- In chemistry, a chemical formula is a way of presenting information about the chemical proportions of titles that constitute a particular chemical emulsion or patch, using chemical element symbols, figures, and occasionally also other symbols, similar as hiatuses, dashes, classes, commas, and plus() and disadvantage( −) signs.
- These are limited to a single typographic line of symbols, which may include subscripts and subtitles.
- A chemical formula may indicate certain simple chemical structures, it isn't the same as a full chemical structural formula.
The subscript number indicates the total number of titles of an element present in a patch.
While witting a chemical formula, first we've to write the symbol of an element and also write the number at the bottom of the symbol.
For illustration,
is the chemical formula of the glucose patch. The glucose patch is made up of six carbon titles, twelve hydrogen titles, and 6 oxygen titles.
The number 6 of the carbon snippet is written after and at the bottom ( lower- right) of the symbol of carbon element (C). also, the number 12 is written lower-right of the symbol of hydrogen element (H), and the number 6 is written lower-right of the symbol of oxygen element( O).
thus, the subscript figures tell us how numerous of the element to their upper-left there are in the patch.

Answer: The expression given simplifies to: 3 .
_________________________________________________
Explanation:
________________________________________________
Given: (3x - 6) / (x-2) ;
___________________________
Factor the numerator into: 3(x-2).
________________________________
Now, rewrite the expression as:
____________________________
;
________________________________________
The "(x - 2)" values cancel to "1" ; since "(x - 2) ÷ (x - 2) = 1" ;
_______________________________________________________
and we are left with: "3 ".
