Question

X al cuadrado - 1/3 = 4/9 - 2/3

Answer 1

Respuesta:

${x}^{2} - \frac{1}{3} = \frac{4}{9} - \frac{2}{3} \\ \frac{9 {x}^{2} }{9} - \frac{3}{9} = \frac{4 - 6}{9} \\ 9 {x}^{2} - 3 = - 2 \\ 9 {x}^{2} = - 2 + 3 \\ 9 {x}^{2} = 1 \\ {x}^{2} = \frac{1}{9} \\ x = \sqrt{ \frac{1}{9} } = + - \frac{1}{3}$
