The correct Answer is:
To find the zeros of the polynomial \( p(x) = (x - 2)^2 - (x + 2)^2 \), we will follow these steps: ### Step 1: Expand the polynomial We start by expanding both squares in the expression. \[ p(x) = (x - 2)^2 - (x + 2)^2 \] Using the identity \( (a - b)^2 = a^2 - 2ab + b^2 \): \[ (x - 2)^2 = x^2 - 4x + 4 \] \[ (x + 2)^2 = x^2 + 4x + 4 \] Now substituting these expansions back into the polynomial: \[ p(x) = (x^2 - 4x + 4) - (x^2 + 4x + 4) \] ### Step 2: Simplify the expression Now, we simplify the expression by distributing the negative sign and combining like terms: \[ p(x) = x^2 - 4x + 4 - x^2 - 4x - 4 \] Notice that \( x^2 \) cancels out: \[ p(x) = -4x - 4x + 4 - 4 \] \[ p(x) = -8x \] ### Step 3: Set the polynomial equal to zero To find the zeros of the polynomial, we set \( p(x) \) equal to zero: \[ -8x = 0 \] ### Step 4: Solve for \( x \) Now, we solve for \( x \): \[ x = 0 \] ### Conclusion Thus, the zero of the polynomial \( p(x) = (x - 2)^2 - (x + 2)^2 \) is: \[ \text{Zero: } x = 0 \] ---
