We have been given an expression 
. We are asked to factor the given expression by grouping.
First of all, we will make two groups of our expression as:
Now we will factor of greatest common factor from each group.
Now we will factor out common terms 
as:
Therefore, the factorized form of our given expression would be .
Answer:
x² + y² = 6.25
Step-by-step explanation:
The standard equation of a circle is ( x – h)² + ( y - k)² = r² where the center is (h, k) and r is the radius.
From your given information that the center is (0, 0) then both h and k are 0. Then r is 2.5, so
( x – 0)² + ( y - 0)² = (2.5)²
x² + y² = (2.5)²
x² + y² = 6.25
The first graph is B. x^2 + 6 < 3
It is a parabola and opens upward when x^2 is positive. 6 raises it upwards by 6 units. the circle at
x = 3 means that the function can approach but not be equal to 3.
