Question

Evaluate the expression for u = 2.

u2 − 17u + 11 =

Answer 1

To evaluate the expression \( u^2 - 17u + 11 \) for \( u = 2 \), we substitute \( 2 \) for \( u \):

\[
u^2 - 17u + 11 = 2^2 - 17(2) + 11
\]

Now, compute each term:

1. \( 2^2 = 4 \)
2. \( -17(2) = -34 \)
3. The constant is \( 11 \)

Now, substitute these values back into the expression:

\[
4 - 34 + 11
\]

Next, perform the arithmetic step by step:

1. \( 4 - 34 = -30 \)
2. \( -30 + 11 = -19 \)

Thus, the result of the expression \( u^2 - 17u + 11 \) for \( u = 2 \) is

\[
\boxed{-19}
\]
