Answer for screen readers
The final answer is (x + y)(x + z)
More Information
The expression (x + y)(x + z) is incorrect because it represents a product of sums, which is characteristic of a POS (Product of Sums) expression rather than an SOP (Sum of Products) expression. An SOP expression contains product terms that are ORed together.
