Which statement is INCORRECT about the relations between analytics methods and proper variable types? Group of answer choices When we have a transaction data, clustering analysis works well. When dependent variable is unknown, we cannot use logistic regression k-means clustering put data to clusters when dependent variable is unknown. When dependent variable is in numeric format, and the dataset includes multiple input variables, we can consider using linear regression.

Example 2 Subtract $ x^{2}-5 x+3 $ from $ 2 x^{2}+5 x-12 $. Solution \[ \begin{array}{l} \left(2 x^{2}+5 x-12\right)-\left(x^{2}-5 x+3\right) \\ =2 x^{2}+5 x-12-x^{2}+5 x-3 \\ =x^{2}+10 x-15 \end{array} \] Exercise 8.5 1. Subtract $ a^{2}-4 a+2 $ from $ 2 a^{2}-a-3 $. 2. Subtract $ x^{2}-3 x-5 $ from $ 2 x^{2}-8 x $. 3. From $ 5 x^{2}-3 x+7 $, subtract $ 2 x^{2}-6 x-4 $. 4. Subtract $ a^{2}-4 a-8 $ from $ -10 a $. 5. From $ -2 b^{2}-4 $, subtract $ -b^{2}-5 $. 6. Subtract $ x^{2}-5 x+1 $ from 8 . 7. Subtract $ -5-2 a $ from $ \left(a^{2}-5 a\right) $. 8. Subtract $ 2 p^{3}-4 p+3 $ from $ 5 p^{3}-9 p+7 $. 9.
