Answer

x = 1, -1

Here are the values of $x$ for each expression in the matrix, assuming each expression is set to zero:

Equation 1: We need to solve the equation $x^2 - 1 = 0$ . Step 1: Add 1 to both sides of the equation. $x^2 = 1$ Step 2: Take the square root of both sides. Remember to consider both positive and negative roots. $x = \pm \sqrt{1}$ $x = \pm 1$ The solutions are $x = 1$ and $x = -1$ . $\boxed{x = 1, -1}$

Equation 2: We need to solve the equation $2x - 4 =

Step 1: Add 1 to both sides of the equation. x^2 = 1 Step 2: Take the square root of both sides. Remember to consider both positive and negative roots. x = ± sqrt(1) x = ± 1 The solutions are x = 1 and x = -1. x = 1, -1 Equation 2: We need to solve the equation $2x - 4 =
