Solve for all real values of x

x² - 16 = 0
+16. +16

x²=16

√x² = ± √16

x= ± 4

Solutions: x=4, x=-4

Answer 1

Sure! Let's solve the equation \( x^2 - 64 = 0 \) step by step.

Solve for all real values of x

\[ x^2 - 64 = 0 \] \[ +64 \quad +64 \]

\[ x^2 = 64 \]

\[ \sqrt{x^2} = \pm \sqrt{64} \]

\[ x = \pm 8 \]

Solutions: \( x = 8, x = -8 \)
