Answer 1

Respuesta:

HOLA (◕‿-)

$(x-5)^{2} = 0$

$x^{2}-10x+5^{2} = 0$

$x^{2}-10x+25 = 0$

Formula general

$\mathrm{Para\:}\quad a=1,\:b=-10,\:c=25:\quad x_{1,\:2}=\frac{-\left(-10\right)\pm \sqrt{\left(-10\right)^2-4\cdot \:1\cdot \:25}}{2\cdot \:1}$

$x_{1,\:2}=\frac{-\left(-10\right)\pm \sqrt{\left(-10\right)^2-(4)(1)(25)}}{2}$

$x_{1,\:2}=\frac{-\left(-10\right)\pm \sqrt{\left(-10\right)^2-100}}{2}$

$x_{1,\:2}=\frac{-\left(-10\right)\pm \sqrt{100-100}}{2}$

$x_{1,\:2}=\frac{-\left(-10\right)\pm \sqrt{0}}{2}$

$x_{1,\:2}=\frac{-\left(-10\right)\pm \sqrt{0}}{2}$

$x=\frac{-\left(-10\right)}{2}$

$x =\frac{10}{2}$

x= 5
