To find:
The mistake in her steps.
Solution:
We have,
The correct steps are shown below.
Step 1: Taking out x as common factor.
Step 2: Now, taking out 2x² as common factor from first two terms (first group of terms) and -1 form last two terms (second group of terms) in the parentheses.
Step 3: Taking out (x+1) as common factor.
She incorrectly factored -1 from the second group of terms.
Therefore, the correct option is B.
Each term is 0.19 more than its predecessor. You have
So, we can assume that the next terms will be
