Q. Solve for xx.\newline(x2)(x3)>0(x - 2)(x - 3) > 0 \newlineWrite a compound inequality like 1<x<31 < x < 3 or like x<1x < 1 or x>3x > 3.
  1. Find Zeros: Find the zeros of the quadratic expression (x2)(x3)(x - 2)(x - 3).(x2)=0(x - 2) = 0 gives x=2x = 2.(x3)=0(x - 3) = 0 gives x=3x = 3.Critical points are 22 and 33.
  2. Determine Intervals: Determine the intervals to test using the critical points.\newlineThe intervals are (,2)(-\infty, 2), (2,3)(2, 3), and (3,)(3, \infty).
  3. Test Interval (,2): (-\infty, 2): Test the interval (,2) (-\infty, 2) by picking a number less than 22, say x=0x = 0.(02)(03)=(2)(3)=6(0 - 2)(0 - 3) = (2)(3) = 6, which is < 0. So, (x - 2)(x - 3) > 0 for xx in (,2) (-\infty, 2) .
  4. Test Interval (2,3)(2, 3): Test the interval (2,3)(2, 3) by picking a number between 22 and 33, say x=2.5x = 2.5.(2.52)(2.53)=(0.5)(0.5)=0.25(2.5 - 2)(2.5 - 3) = (0.5)(-0.5) = -0.25, which is < 0. So, (x2)(x3)(x - 2)(x - 3) is not > 0 for xx in (2,3)(2, 3).
  5. Test Interval (3,):</b>Testtheinterval$(3,)(3, \infty):</b> Test the interval \$(3, \infty) by picking a number greater than 33, say x=4x = 4.(42)(43)=(2)(1)=2(4 - 2)(4 - 3) = (2)(1) = 2, which is > 0.\newlineSo, (x - 2)(x - 3) > 0 for xx in (3,)(3, \infty).
  6. Combine Intervals: Combine the intervals where (x - 2)(x - 3) > 0. The solution is xx in (,2)(-\infty, 2) or (3,)(3, \infty).
