Question

Amigosss ayuda con esto por favor

Answer 1

Respuesta:

${a}^{2} + 25 = 0 \\ {a}^{2} = - 25 \\ a = \sqrt{ - 25} \\ a = + 5 \\ a = - 5$

${y}^{2} + 144 = 0 \\ {y}^{2} = - 144 \\ y = \sqrt{ - 144 } \\ y = + 12 \\ y = - 12$

$- {x}^{2} - 5 = - 35 - {4x}^{2} \\ 30 = {3x}^{2} \\ 10 = {x}^{2} \\ \sqrt{10} = x$

${m}^{2} + \frac{1}{25} = \frac{3}{5} \\ {m}^{2} = \frac{3}{5} - \frac{1}{25} \\ {m}^{2} = \frac{15 - 1}{25} \\ {m}^{2} = \frac{14}{25}$

${4r}^{2} + 9 = 0 \\ {4r}^{2} = - 9 \\ {r}^{2} = \frac{ - 9}{4} \\ r = \frac{ - 3}{2}$

$7 - {s}^{2} = 71 \\ {s}^{2} = 71 \\ {s}^{2} = - 64 \\ s = - 8$
