X= 11/2 creo JAJSHSKHSHSSKJDSJS

Answer 2

Respuesta:

$\left(x-3\right)^2=5\\\\x^2-2x\cdot \:3+3^2 =5\\\\x^2-6x+9 =5\\\\x^2-6x+9-5=0\\\\x^2-6x+4=0$

Aplica la formula general

$x_{1,\:2}=\frac{-\left(-6\right)\pm \sqrt{\left(-6\right)^2-4\cdot \:1\cdot \:4}}{2\cdot \:1}\\\\x_{1,\:2}=\frac{-\left(-6\right)\pm \:2\sqrt{5}}{2\cdot \:1}\\\\x_1=\frac{-\left(-6\right)+2\sqrt{5}}{2\cdot \:1},\:x_2=\frac{-\left(-6\right)-2\sqrt{5}}{2\cdot \:1}\\\\x_{1} =\frac{6+2\sqrt{5}}{2\cdot \:1}\\\\x_{1} =\frac{6+2\sqrt{5}}{2}\\\\x_{2} =\frac{6-2\sqrt{5}}{2\cdot \:1}\\\\x_{2} =\frac{6-2\sqrt{5}}{2}$
