The difference is .
Step-by-step explanation:
Step 1:
The polynomial is subtracted from the polynomial .
If we write this as an equation, we get
.
To subtract the polynomials, we group up the terms based on their variables.
In this subtraction, there are two variables i.e. and and there is one constant term.
Step 2:
The subtraction of the variables; .
The subtraction of the variables; .
The subtraction of the constants; .
So .
Step-by-step explanation:
This means that if a line is perpendicular to a line that has slope m, then the slope of the line is -1 / m. For example, we found that the slope of the line y = (1/2)x + 3 is 1/2. Thus any line that is perpendicular to this line would have slope -2 /1 = -2.
