Regla general​

Answer 1

Respuesta:

x1= 5,  x2= 5

Explicación paso a paso:

x²-10x+25=

$x =-(-10)\frac{+}\\ \frac{\sqrt{-10^{2} -4(1)(25)}}{2(1)} \\x =-(-10)\frac{+}\\ \frac{\sqrt{100 -100}}{2} \\x =-(-10)\frac{+}\\ \frac{\sqrt{0}}{2} \\x =-(-10)\frac{+}\\ \frac{0}{2} \\x =10\frac{+}\\ \frac{0}{2} \\x1= \frac{10+0}{2} \\x1= 5\\x2= \frac{10-0}{2} \\x2= 5$
