Question

me ayudan con esto xfaaa​

Answer 1

Solo recuerda:

${x}^{2} = {a}^{2} \\ |x| = a \\ x = a \: \: \: o \: \: \: x = - a \\ a \geqslant 0$

...

${(x - \frac{1}{2} )}^{2} = \frac{1}{2} + \frac{7}{4} \\ {(x - \frac{1}{2} )}^{2} = \frac{9}{4} \\ |x - \frac{1}{2} | = \frac{3}{2} \\ x - \frac{1}{2} = \frac{3}{2} \: \: \: o \: \: \: x - \frac{1}{2} = - \frac{3}{2} \\ x = 2 \: \: \: o \: \: \: x = - 1$
