Question

Me explican esta paso a paso porfa voor es el ultimo ejercicio que me queda

Answer 1

( x² - 6)/2 - (x² +4)/4 = 5

[2(x² - 6) - (x²+4)]/4 = 5
2x² - 12 - x² - 4 = 4×5
X² - 16 = 20
X² = 20 + 16
X² = 36
X = ±√36
X = ± 6
X= 6 y X=-6

Answer 2

$\frac{ x^{2} -6}{2} - \frac{ x^{2} +4}{4} = 5$

$2( x^{2} -6)-( x^{2} +4) = 20$

$2 x^{2} -12- x^{2} -4 = 20$

$x^{2} -16 = 20$

$x^{2} = 36$

$\sqrt{ x^{2} } = \sqrt{36}$

$x = 6$   ∨    $x = -6$
