a²+2a+36=0
atyudaaaaaaaaaaaaaaaaaaaaaaaaaaa

Answer 1

Explicación paso a paso:

a^2+2a+36=0

$a_{1,\:2}=\frac{-2\pm \sqrt{2^2-4\cdot \:1\cdot \:36}}{2\cdot \:1}$

$a_{1,\:2}=\frac{-2\pm \:2\sqrt{35}i}{2\cdot \:1}$

$a_1=\frac{-2+2\sqrt{35}i}{2\cdot \:1},\:a_2=\frac{-2-2\sqrt{35}i}{2\cdot \:1}$

$a=-1+\sqrt{35}i,\:a=-1-\sqrt{35}i$
