select the correct answer. solve the following equation for x. $x^{2}-36 = 0$ a. $x = 1;x=-36$ b. $x=-1;x = 36$ c. $x=-6;x = 6$ d. $x=-18;x = 18$

select the correct answer. solve the following equation for x. $x^{2}-36 = 0$ a. $x = 1;x=-36$ b. $x=-1;x = 36$ c. $x=-6;x = 6$ d. $x=-18;x = 18$

Answer

Explanation:

Step1: Reorganizar la ecuación

Sumamos 36 a ambos lados de la ecuación $x^{2}-36 = 0$, obteniendo $x^{2}=36$.

Step2: Hallar la raíz cuadrada

Tomamos la raíz cuadrada de ambos lados. Recordando que $\sqrt{x^{2}}=\pm x$, tenemos $x=\pm\sqrt{36}$, es decir $x = 6$ o $x=-6$.

Answer:

C. $x = - 6;x = 6$
