X+2/7=2/x-2
Explíquenmelo plissss

Answer 1

$\frac{x+2}{7} = \frac{2}{x-2} \\ \\ (x+2)(x-2)= 7*2 \\ \\ x^2-2x+2x-4=14 \\ \\ x^2-4=14 \\ \\ x^2= 14+4 \\ \\ x= \pm \sqrt{18} \\ \\ x_1= \sqrt{18}\qquad \qquad \quad \ x_2=- \sqrt{18} \\ \\ x_1= \sqrt{2*3^2}\qquad \qquad x_2=- \sqrt{2*3^2} \\ \\ x_1= 3\sqrt{2}\qquad \qquad\quad\ x_2=- 3\sqrt{2} \\ \\ x_1=4,24....\qquad\qquad\ x_2= -4,24....$
