Question

$x^{2} +2x+1=0$

Answer 1

Respuesta:

x = -1

Explicación paso a paso:

x² + 2x + 1 = 0

x = $\frac{-2+\sqrt{2^2-4(1)\times1} }{2(1)}$

x = $\frac{-2+\sqrt{2^2-4} }{2(1)}$

x = $\frac{-2+\sqrt{4-4} }{2(1)}$

x = $\frac{-2+\sqrt{0} }{2(1)}$

x = $\frac{-2}{2(1)}$

x = $\frac{-2}{2}$

x = -1
