<p>I got this question wrong on a practice test for the Blue Book, but the College Board Blue Book doesn't explain wrong answers, and I haven't been able to solve this after going back to the questions I got wrong.</p>

<p>(x-8)(x-k)=x^2-5kx+m</p>

<p>In the equation above, k and m are constants. If the equation is true for all values of x, what is the value of m?</p>

<p>A. 8
B. 16
C. 24
D. 32
E. 40</p>

<p>Maybe the mistake was trying to solve it algebraically. I didn't try plugging in answers yet, but could you try to come up with an algebraic solution?</p>
