The correct Answer is:
To solve the question, we need to verify the two statements provided and determine if they are true and if one explains the other. ### Step 1: Verify Statement 1 We need to check if \( x = 1 \) is a root of the quadratic equation: \[ (2^{10} - 3)x^2 - 2^{11}x + (2^{10} + 3) = 0 \] Substituting \( x = 1 \): \[ (2^{10} - 3)(1^2) - 2^{11}(1) + (2^{10} + 3) = 0 \] This simplifies to: \[ (2^{10} - 3) - 2^{11} + (2^{10} + 3) = 0 \] Combining like terms: \[ 2^{10} - 3 - 2^{11} + 2^{10} + 3 = 0 \] The \(-3\) and \(+3\) cancel out: \[ 2^{10} + 2^{10} - 2^{11} = 0 \] This can be rewritten as: \[ 2 \cdot 2^{10} - 2^{11} = 0 \] Since \(2^{11} = 2 \cdot 2^{10}\), we have: \[ 2^{11} - 2^{11} = 0 \] Thus, Statement 1 is confirmed to be true. ### Step 2: Verify Statement 2 Statement 2 claims that if the sum of the coefficients of a quadratic equation is zero, then \( x = 1 \) is a root. Let the quadratic equation be represented as: \[ ax^2 + bx + c = 0 \] The sum of the coefficients is: \[ a + b + c \] If \( a + b + c = 0 \), we substitute \( x = 1 \): \[ a(1^2) + b(1) + c = a + b + c = 0 \] Thus, if the sum of the coefficients is zero, \( x = 1 \) is indeed a root. Therefore, Statement 2 is also confirmed to be true. ### Step 3: Explanation of Statements Since Statement 1 is true and Statement 2 correctly explains why \( x = 1 \) is a root of the quadratic equation given in Statement 1, we conclude that both statements are true, and Statement 2 is the correct explanation of Statement 1. ### Conclusion Both statements are true, and Statement 2 explains Statement 1. Therefore, the answer is that both statements are correct, and Statement 2 is the correct explanation of Statement 1. ---
