Beyond the Answer
First, let's distribute the negative sign to the second polynomial and simplify: \[ (14y^2 + 8y - 5) - (6y^2 - 3y + 17) = 14y^2 + 8y - 5 - 6y^2 + 3y - 17 \] Now, combine like terms: \[ (14y^2 - 6y^2) + (8y + 3y) + (-5 - 17) = 8y^2 + 11y - 22 \] The correct answer is: **B.** \(8 y^{2}+11 y-22\) Now, here's a quick tip: Keep an eye out for distributing the negative sign carefully; it’s a common mistake to forget to flip the signs!
