4x²+64=0 ajudaa......​

Answer 1

$\LARGE\tt{} {4x}^{2} + 64 = 0 \\ \LARGE\tt{} {x}^{2} + 16 = 0 \\\LARGE\tt{} {x}^{2} = - 16 \\\LARGE\tt{}x = \pm \: 4i \\ \LARGE\tt{}x = - 4i \\ \LARGE\tt{}x = 4i \\ \LARGE\tt{} x_{1} = - 4i \\ \LARGE\tt{} x_{2} = 4i \\ \\ \\\LARGE\tt{}s \{ x_{1} = - 4i, x_{2} = 4i \}$
