Question

10x²+3= 1o
Operación y comprobación

Answer 1

Respuesta:

$10 {x}^{2} + 3 = 10 \\ 10 {x}^{2} = 10 - 3 \\ 10 {x}^{2} = 7 \\ {x}^{2} = \frac{7}{10} \\ \sqrt{ {x}^{2} } = \sqrt{ \frac{7}{10} } \\ x = \sqrt{ \frac{7}{10} } \\ comprobación \\ 10 ({\sqrt{(\frac{7}{10}})^{2}} ) + 3 = 10\\ 10 (\frac{7}{10} ) + 3 = 10\\ \frac{70}{10}+3=10</p><p>\\ 7+3=10$
