Answer 2

It seems like you've provided four different quadratic expressions, and I can help you factor them:

2. b^2 + 3b - 28: To factor this quadratic expression, we need to find two numbers that multiply to -28 and add up to 3. These numbers are 7 and -4. So, the factored form is (b + 7)(b - 4).

3. y^2 - 5y + 6: To factor this quadratic expression, we need to find two numbers that multiply to 6 and add up to -5. These numbers are -2 and -3. So, the factored form is (y - 2)(y - 3).

4. n^2 - n - 110: To factor this quadratic expression, we need to find two numbers that multiply to -110 and add up to -1. These numbers are -11 and 10. So, the factored form is (n - 11)(n + 10).

5. t^2 - 2t - 63: To factor this quadratic expression, we need to find two numbers that multiply to -63 and add up to -2. These numbers are -9 and 7. So, the factored form is (t - 9)(t + 7).
