The first step for simplifying the above fraction is to divide the terms with the same base by subtracting their exponents.

Remember that when there is a
"-" sign in front of the parenthesis,, we need to change the sign of each term in the parenthesis. This changes the fraction to the following:

Calculate the sum of the exponents.

Lastly,, reduce the fraction with 3 to find your final answer.

Answer:
(x-4)^2 + (y-2)^2 = 3^2
or
(x-4)^2 + (y-2)^2 = 9 (simplified if needed)

Answer:
The second option
Step-by-step explanation:
Here, we need to multiply each part of the matrix by -10.
This will give us: [ -230 380 ]
[ -170 60 ]
So, the answer is the second option.
