2(x^2 +36) +14 =38
2(x^2+36) =38-14
x^2 + 36= 24\2
x^2 +36 = 12
x^2 =12-36
x^2 = -24
tkaing square root on both sides
\[\sqrt{x ^{2}}=\sqrt{2 \times 2 \times 2 \times-3 }\]
\[x = 2 \sqrt{-6} \]
or
x=\[x = 2\sqrt{6}\iota \]
so the root is imaginary

THANKS !!!! :)
OpenStudy (yttrium):
You sure @Haseeb96 ?
OpenStudy (haseeb96):
yes 100%
OpenStudy (yttrium):
2|x-6| = 24
|x-6| = 12
consider two cases again
x-6 = 12
-(x-6) = 12
x = 18
and
x = -6

It's just about absolute values. @Haseeb96
OpenStudy (haseeb96):
yttrium there first we apply Modulus
OpenStudy (haseeb96):
I x -6 I = 12
I I is the sign of modulus
OpenStudy (yttrium):
is it really modulus @Goldenmoon or and absolute value?
what your lesson is?
OpenStudy (anonymous):
The answer was wrong , its absolute value :/ sorry
