When is subtracted from
then the result is
Given that is subtracted from
We have to find the result
Subtraction is a mathematical operation that tells us the difference between two numbers.
When "a" is subtracted from "b", we write in mathematical expression as "b - a"
So is subtracted from
is written mathematically as:
<em><u>Expanding the above expression using algebraic identity:</u></em>
Multiplying the nnegative sign with terms inside bracket
<em><u>There are two simple rules to remember: </u></em>
- When you multiply a negative number by a positive number then the product is always negative.
- When you multiply two negative numbers or two positive numbers then the product is always positive.
Hence the result is:
There is no single solution but there is a group of solutions also known as the interval.
This can be written with an interval.
Hope this helps.
