Question

Me pueden pasar el procedimiento

x²- 25 = 0

x²-84=0

x²-100=0​

Answer 1

Respuesta:

${x}^{2} - 25 = 0 \\ {x}^{2} = 25 \\ x = \sqrt{25 \\ } \\ x = 5 \\ x = - 5$

${x}^{2} - 84 = 0 \\ x = \sqrt{84} \\ x = 2 \sqrt{21 \\ } \\ x = - 2 \sqrt{21}$

${x}^{2} - 100 = 0 \\ {x}^{2} = 100 \\ x = \sqrt{100} \\ x = 10 \\ x = - 10$
