Solve for x over the real numbers:
2 x^2 - 4 x - 3 = 0
Divide both sides by 2:
x^2 - 2 x - 3/2 = 0
Add 3/2 to both sides:
x^2 - 2 x = 3/2
Add 1 to both sides:
x^2 - 2 x + 1 = 5/2
Write the left hand side as a square:
(x - 1)^2 = 5/2
Take the square root of both sides:
x - 1 = sqrt(5/2) or x - 1 = -sqrt(5/2)
Add 1 to both sides:
x = 1 + sqrt(5/2) or x - 1 = -sqrt(5/2)
Add 1 to both sides:
Answer: x = 1 + sqrt(5/2) or x = 1 - sqrt(5/2)
Based on the coordinates of line BC, the coordinates of N, and the fact that O is not on the coordinate plane, the coordinates of O are (6, 5).
<h3>What are Point O's coordinates?</h3><h3 />
Point N is a reflection of B and point O is a reflection of C. This means that N to O will be a straight line.
Because O is not on the Coordinate plane, we would need to draw a diagonal line from N towards C.
A vertical line should then be drawn from Point C downwards.
These two lines will intersect at (6, 5). This will be the coordinates of Point O.

when it says nearest ten you ignore the decimals and look at 90998 the nearest ten of 998 is 1000 so keep the nine at the beginning and you have 91000
