Answer:
x = -1 ± √3
Step-by-step explanation:
3x² − 2x − 1 = x² − 6x + 3
Move everything to one side.
2x² + 4x − 4 = 0
Divide by 2.
x² + 2x − 2 = 0
Solve with quadratic formula, or by completing the square.
x² + 2x = 2
x² + 2x + 1 = 3
(x + 1)² = 3
x + 1 = ±√3
x = -1 ± √3
Consider we need to find the equation of the circle.
Given:
The Center at (-4,-1), radius = 2.
To find:
The equation of the circle.
Solution:
The standard form of a circle is

Where, (h,k) is the center of the circle and r is the radius of the circle.
Putting h=-4, k=-1 and r=2, we get


Therefore, the equation of the circle is
.
A rational number is any number that can be turned into a fraction....it can be negative or positive.
Therefore, -12/6 is a rational number
