Consider the expression –3(y – 5)2 – 9 + 7y.Which statements are true about the process and simplified product? Check all that apply.

First square the binomial: (y − 5)² = y² − 10y + 25. Then multiply by −3 and combine like terms: −3y² + 30y − 75 − 9 + 7y = −3y² + 37y − 84. This has three terms, so B is true, and it matches choice E. The polynomial has degree 2, not degree 3; also, the exponent means you square the binomial before multiplying by −3.
