How to write expression by writing the soul it on in unit for and standard form
To write an expression in word form, you need to convert it to an equation and then describe it using words. On the other hand, to write an expression in standard form, you arrange its terms in descending order of powers and simplify it if necessary. Let's look at an example to understand each process better.
Example:
Expression - 2x + 3(y - 4)
To write this expression in word form, you need to describe the equation it represents:
1. Start by breaking down the expression:
2x represents "twice the value of x"
3(y - 4) represents "three times the quantity of y minus four"
2. Combine the descriptions:
Overall, the expression can be written as "twice the value of x plus three times the quantity of y minus four."
Now let's move on to writing the expression in standard form:
1. Expand the expression by distributing the 3 to (y - 4):
2x + 3y - 12
2. Arrange the terms in descending order of powers:
3y + 2x - 12
3. Simplify the expression if necessary:
The expression is already in its simplest form, so no further simplification is needed.
Therefore, the expression 2x + 3(y - 4) can be written in word form as "twice the value of x plus three times the quantity of y minus four," and in standard form as 3y + 2x - 12.
