Question

como hago:
${(x + \frac{3}{4} )}^{2} + \frac{5}{4} = \frac{21}{16}$
​

Answer 1

Respuesta:

Explicación paso a paso:

$\left(x+\frac{3}{4}\right)^{2}+\frac{5}{4}=\frac{21}{16}\\\\\left(x+\frac{3}{4}\right)^{2}=\frac{21}{16}-\frac{5}{4}\\\\\left(x+\frac{3}{4}\right)^{2}=\frac{1}{16}\\\texttt{Extrayendo ra\'iz cuadrada en ambos lados:}\\\\\sqrt{\left(x+\frac{3}{4}\right)^{2}}=\sqrt{\frac{1}{16}\\\\x+\frac{3}{4}=\frac{1}{4}\\\\x=\frac{1}{4}-\frac{3}{4}\\\\x=-\frac{2}{4}=-\frac{1}{2}$
