Explicación paso a paso:
[tex] \frac{1}{2} {x}^{2} + 3 = 11 \\ \frac{ {x}^{2} }{2} + 3 = 11 \\ \frac{ {x}^{2} }{2} = 11 - 3 \\ \frac{ {x}^{2} }{2} = 8 \\ {x }^{2} = 2 \times 8 \\ {x }^{2} = 16 \\ \sqrt{ {x}^{2} } = \sqrt{16} \\ |x | = 4 \\ x = + - 4[/tex]
[tex] \frac{ {4}^{2} }{2} + 3 = \frac{16}{2} + 3 = 8 + 3 = 11[/tex]
[tex] \frac{ { - 4}^{2} }{2} + 3 = \frac{16}{2} + 3 = 8 + 3 = 11[/tex]
espero te sirva
