Step 1
Step-by-step explanation:
When you subtract a polynomial in parentheses, you have to remove them from the parentheses first, which Kenisha did right. The problem is that because the numbers are being subtracted, all of the signs switch, which they forgot to do. Step one should look like: 2b² + 3b + 11 - 7b² + 5b - 1
