We are given that the product of the two roots are 32, so I started looking at the different possibilities. 8 * 4, 8*4, 16 * 2, 16 * 2, 32 * 1, and 32 * 1.
First I plugged x=8 into the equation and got that
64K=5504.
So K=86.
Then I checked its pair, x=4. Plugging this in I got
16K=1376.
So K=86.
Since both x=8 and x=4 give the same K value, K=86 is the solution.
