what are the solutions to the quadratic equation x² - 16 = 0?\no x = 2 and x = -2\no x = 4 and x = -4\no x = 8 and x = -8\no x = 16 and x = -16
Answer
Explanation:
Step1: Isolate the variable term
Add 16 to both sides of the equation $x^{2}-16 = 0$. We get $x^{2}=16$.
Step2: Take square - root of both sides
$x=\pm\sqrt{16}$. Since $\sqrt{16} = 4$, then $x = 4$ or $x=-4$.
Answer:
$x = 4$ and $x=-4$ (the second option)
