Answer

A (x-3)(x-4) Explanation 1. Identify the factors of the constant term The constant term is 12. Find pairs of factors that multiply to 12: (1, 12), (2, 6), (3, 4). 2. Check sum of factor pairs Find a pair whose sum equals the coefficient of the linear term (-7): (3, 4) since 3 + 4 = 7. 3. Determine signs for factoring Since the middle term is negative and the constant is positive, both factors must be negative: (-3, -4). 4. Write the factored form Use the identified factors: (x-3)(x-4).
