\(\displaystyle y = -x^2 + 6x - 8, y = 0\)

so I got -8 to 0 for the integral by plotting the graph... How are they getting 2 to 4? You can't solve that by factoring? And when i plugged it into the quadratic formula i got 1 to 5

nevermind my god im stupid I forgot to distribute the xThe region bounded by the given curves is rotated about the specified axis. Find the volume of the resulting solid by any method..

Actually I take that back, I still don't understand how they get 2 to 4.
