X + 1 / X is equal to the value of six times the square of x plus 1 / 2 of X

X + 1 / X is equal to the value of six times the square of x plus 1 / 2 of X

x+1/x=6
x²+1/x²+2=36
∴x²+1/x²=34

If X-Y = 2, X to the second power - y to the second power = 10, then what is 4x + 6?

x^2-y^2=(x+y)(x-y)=10
x+y=5
∴x=3.5
4x+6=20

If the square of the absolute value of 4x-y + 4 + (2x + Y-10) equals zero, then x =?

According to the meaning of the title, 6x-6 = 0 & nbsp; X = 1

If the square of x plus the square of y plus 2 times x minus 6 times y plus 10 equals 0, then x minus y equals 0

X ^ 2 + 2x + 1 + y ^ 2-6y + 9 = 0
(x+1)^2+(y-3)^2=0
x+1=0,y-3=0
x=-1,y=3
x-y=-1-3=-4

10 minus 12 times a number, the difference is 4, set up equations, find the solution of the equation

10-12x=4
12x=10-4
12x=6
x=1/2

How many meters is 6 feet 10 inches
This is the height of the NBA rockets rookie ~ how high is the conversion?

1 foot = 12 inches = 0.3048 meters
1 inch = 2.5400 cm
6 feet 10 inches equals 2.0828 meters

Xiao Ning read a story book. On the first day, he read one third of the whole book. On the second day, he read three fifths of the whole book. On the second day, what percentage of the whole book?

On the first day, I read 1 / 3 of the whole book and 3 / 5 of the first day
Using multiplication to do 1 / 3 * 3 / 5 = 1 / 5
A: I read one fifth of the whole book the next day

Find the value of | 1 / 3-1 / 2 | + | 1 / 4-1 / 3 | + 1 / 5-1 / 4 | +. + | 1 / 2012-1 / 2011 |

The original formula = [(1 / 2) - (1 / 3)] + [(1 / 3) - (1 / 4)] + [(1 / 4) - (1 / 5)] + +[(1/2011)-(1/2012)]
=(1/2)-(1/2012)
=(1006-1)/2012
=1005/2012.

The car and the truck set out at the same time and went in opposite directions. After 1.3 hours, the cars were 168 kilometers apart. After 2.5 hours, the two cars met on the way. How many kilometers are there between the two places? One yuan

The distance between the two places is x km: X / 2.5 = 168 / (2.5-1.3)
x=350

Two sides of a triangle are 1 and 2, and the third side is exactly 2x ^ 2 - 5x + 3 = 0
^2 means square
I'll score. Thank you··············
The two sides of a triangle are 1 and 2, and the third side is exactly the root of 2x ^ 2 - 5x + 3 = 0

Equation: 2x & # 178; - 5x + 3 = 0
(2x－3)(x－1)=0
X = 3 / 2 or x = 1
Then the third side of the triangle is 3 / 2, and the perimeter is 1 + 2 + (3 / 2) = 9 / 2
