- Guess I'm back now, well, go on with your explanation.
- -x-2 + 80x - 1500 > 0
- Before we go to the answer, first we need to make it into a quadratic equation. So, it will become -x-2 + 80x - 1500 = 0.
- Then from the equation, we should "factor" the left side of it, so it will become (x+30) (x-50) = 0.
- We need to reverse the inequality first, so we multiply both of the sides by -1.
- After that, we need to test the values in the interval in order for us to see if it works.
- x < 30 and x < 50 doesn't work with the original inequalities though.
- Nice job! I understand it now, thanks to you. Thank you very much!
- It is my pleasure boss!
