what are the solution(s) to the quadratic equation 40 - x² = 0?\n○ x = ±2√10\n○ x = ±4√10\n○ x = ±2√5\n○ x = ±4√5

Answer

Explanation:

Step1: Re - arrange the equation

Mover $x^{2}$ al otro lado de la ecuación: $x^{2}=40$

Step2: Obtener la raíz cuadrada de ambos lados

$x = \pm\sqrt{40}$

Step3: Simplificar la raíz cuadrada

$\sqrt{40}=\sqrt{4\times10}=2\sqrt{10}$, entonces $x=\pm2\sqrt{10}$

Answer:

$x = \pm2\sqrt{10}$
