Question

10x²-12+1=-10x² решите уравнение ​

Answer 1

Объяснение:

$10x { }^{2} - 12 + 1 = - 10x \\ 10x {}^{2} - 11 = - 10x {}^{2} \\ 10x {}^{2} + 10x {}^{2} = 11 \\ 20x {}^{2} = 11 \\ x = \frac{11}{20} \\ x = + - \frac{ \sqrt{55} }{10} \\ x1 = - \frac{ \sqrt{55} }{10} \\ x2 = \frac{ \sqrt{55} }{10}$
