What does x equal?
2(x+5)^2/ 12 = 2.166
Thanks for the help in advance.
2(x+5)^2/ 12 = 2.166
Thanks for the help in advance.
-
2(x+5)^2/ 12 = 20.166
(x+5)^2 = 120.996
x+5 = ±11
x = 6 or -16
(x+5)^2 = 120.996
x+5 = ±11
x = 6 or -16
-
[2(x+5)^2]/12 = 2.166
basically you want to distribute your x terms as much as possible, group every value on one side and then factor the find your x-values (or quadratic formula if it doesn't factor easily)
So distribute x terms
[2(x+5)^2]/12 - I also simplify the 2/12 part
(x^2+10x+25)/6 = 2.166
x^2 + 10x + 25 = 13
Now group everything on one side
x^2 + 10x + 12
and factor
x^2 + 10x +12
(x + )(x + )
This doens't factor easily... quadratic formula!
A = 1
B = 10
C = 12
x = -1.394, -8.606
So x equals -1.394 or -8.606

Multiply both sides by 12. (I assume that 20.166 is really 20 & 2/3)
2(x + 5)^2 = 248
(x + 5)^2 = 124
(x + 5) = sqrt(4) * sqrt(31)
(x + 5) = +/-2sqrt(31)
x = -5 +/- 2sqrt(31)
The answer is roughly 11.

x = -8.605
x = -1.395
x = -1.395
