The first step for solving this expression is to write the division as a fraction.
x +
× x
Calculate the product.
Remember that if a term doesn't have an exponent,, it is considered that the exponent for that term is 1. This changes the expression to the following:
Now multiply the terms with the same base by adding their exponents.
Finally,, add the numbers together to get your final answer.
x +
Let me know if you have any further questions.

Answer:
Standard form:
Center:
Radius:
Step-by-step explanation:
The equation of a circle in the standard form is
Where the point (h, k) is the center of the circle
To transform this equation this equation in the standard form we use the method of square.
First, we group similar variables
Divide both sides of equality by 4
Now we complete square for variable x.
Take the coefficient "b" that accompanies the variable x and divide by 2. Then, elevate the result to the square:
Now add on both sides of the equality
Factor the expression and simplify the independent terms
Then
and the center is
radius
