Expression Analysis: We are given the expression (x−3)2−10(x−3)+25 and asked to identify a factoring pattern that can be used to factor it. Let's first rewrite the expression to see if it resembles any common factoring patterns.
Perfect Square Trinomial: The given expression is a quadratic in the form of a perfect square trinomial. A perfect square trinomial is an expression that can be written as A+B^2 or A−B^2, where A and B are expressions. The standard form of a perfect square trinomial is A2±2AB+B2.
Comparison with Standard Form: Let's compare the given expression with the standard form of a perfect square trinomial. We have A=(x−3) and we need to find B such that the expression matches A2−2AB+B2. We can see that A2 is (x−3)2, and B2 should be 25, which means B is 5 since 52=25.
Matching the Middle Term: Now, we need to check if the middle term −10(x−3) matches the −2AB term in the perfect square trinomial pattern. For our expression, A is (x−3) and B is 5, so −2AB would be −2⋅(x−3)⋅5, which simplifies to −10(x−3).
Factoring Using the Pattern: Since the given expression matches the pattern A2−2AB+B2, where A is (x−3) and B is 5, we can factor it using the pattern (A−B)2. Therefore, the factored form of the expression is ((x−3)−5)2 or (x−3−5)2, which simplifies to (x−8)2.
Successful Factoring: We have successfully factored the expression using the pattern (A−B)2. This corresponds to choice A from the given options, which are (U+V)2 or (U−V)2.
