Question

1/2-3/5(X^2+2/9)=3/10 solución

Answer 1

Respuesta:

±1/3

Explicación paso a paso:

$\frac{1}{2} -\frac{3}{5} *(x^{2} +\frac{2}{9} )=\frac{3}{10} \\\frac{1}{2} -\frac{3}{5}x^{2}-\frac{2}{15}=\frac{3}{10}\\\frac{3}{5}x^{2}=\frac{1}{2} -\frac{2}{15}-\frac{3}{10}\\\frac{3}{5}x^{2}=\frac{1}{15} \\x^{2} =\frac{1}{15}*\frac{5}{3}\\x^{2} =\frac{1}{9} \\x= \sqrt{\frac{1}{9} } =\frac{1}{3}$
