To perform the division of the polynomial \( \frac{y^2 + 2y + 11}{y + 6} \), we can use polynomial long division.
1. Divide the leading term of the numerator \( y^2 \) by the leading term of the denominator \( y \):
\[
y^2 \div y = y
\]
2. Multiply the entire divisor \( y + 6 \) by this result \( y \):
\[
y(y + 6) = y^2 + 6y
\]
3. Subtract this from the original numerator:
\[
(y^2 + 2y + 11) - (y^2 + 6y) = 2y + 11 - 6y = -4y + 11
\]
4. Now, we take the new polynomial \(-4y + 11\) and repeat the process. Divide the leading term \(-4y\) by \(y\):
\[
-4y \div y = -4
\]
5. Multiply the entire divisor \(y + 6\) by \(-4\):
\[
-4(y + 6) = -4y - 24
\]
6. Subtract this from \(-4y + 11\):
\[
(-4y + 11) - (-4y - 24) = 11 + 24 = 35
\]
Now, we are left with a remainder of \(35\).
Combining all parts, the result of the division is:
\[
y - 4 + \frac{35}{y + 6}
\]
So, the final answer is:
\[
\frac{y^2 + 2y + 11}{y + 6} = y - 4 + \frac{35}{y + 6}
\]
