Question

3(x+2)(x-2)=(x-4)2 +8​

Answer 1

Respuesta:

X1 = 1 - ✓37/3 y X2 = 1 + ✓37/3

Explicación paso a paso:

$3(x + 2)(x - 2) = (x - 4)2 + 8 \\ (3x + 6)(x - 2) = 2x - 8 + 8 \\ 3x {}^{2} - 6x + 6x - 12 = 2x \\ 3x {}^{2} - 12 = 2x \\ 3x {}^{2} - 2x - 12 = 0 \\x = \frac{1 - \sqrt{37} }{3} \\ x = \frac{1 + \sqrt{37} }{3}$
