Man, it's already been a month since I started watching your vids on geometry and algebra and I can already feel the smartness oozing out of my brain.🧠
For anyone struggling to find the last two comprehension. Know that before you start trying to solve x, you have to get the absolute value by itself. Example: |2x +8| -2 = 14 becomes |2x +8| = 16. Now from here you have to split it into two equations, |2x +8| = 16 and |2x +8| = -16. From here you can just simply solve it like before. Goodluck
Answer of 3rd comprehension (negative case) : -------------------------------------------------- We start with the equation |2x + 8| - 2 = 14. Substituting -(2x + 8) for |2x + 8|, we have -(2x + 8) - 2 = 14. To solve this equation, we simplify it step by step: * Distribute the negative sign to each term inside the parentheses: -2x - 8 - 2 = 14. * Combine like terms: -2x - 10 = 14. * Add 10 to both sides to isolate the variable term: -2x = 24. * Finally, divide both sides by -2 to solve for x: x = -12.
i grew to love math because your videos made me appreciate the beauty and importance of the subject. just a little more and soon, i'll be laughing my ass off at some math jokes 🤣anyways, thank you so much, professor dave! please continue to feed others with knowledge and curiosity :)
I'm a little bit late, however I'll answer to you. As an engineer, when we're calculating areas with integrals, we use absolute values. Depending on the functions we'll have to work with, the value might be negative. Notwithstanding, it's impossible to have a negative area. That's why's it important to have a mathematical tool like absolute value
Hey Prof. Thank you for the work you do, very much appreciated. Will you look into discreet mathematic topics. I would love to see your video tutorials on topics like logic, truth tables, combinations, series and sequences or any one of these. Thank you
I got the solution by dealing with the -2 first since its not absolute, you get 16 and then you turn it into -16 (since its the second solution with a negative sign) and -16 -8 is -24 /2 is -12
@@xezed even when i have moved the numbers and asolute value to sides it didnt work correct like the first two, but when seeing @meryemtib948 solution it make sense but cant understand how and when or at what point to calculate if |2x+8| >= 0 or |2x + 8|
am really stunned with the comprehensions always couple of them doing them wrong and cant understand if it me doing something wrong or incomplete info how to solve them in the video, read all the comments seems there is another way if its with another variable and needs to evaluate if the absolute value is more or less than 0 to apply the negative it seems the correct one but how to implement it dont know hmmmm

@@huzaifaali3969 You gotta move the negative 2 first and then do the absolute value, and it's the same with 10. Absoulte value on one side and the other numbers on the other side.

1:10 does it apply to imaginary numbers? If so, how does it work, does -i become i or does it become something like -1 or 1.
I can feel the math coming inside of me

his study qualifications are yes.
because he doesnt waste time on games and other stuff he had none back on his time
for the 3rd question l2x+8l=14 i keep getting 4 and -10 not 4 and -12 any idea why?
I got the solution by dealing with the -2 first since its not absolute, you get 16 and then you turn it into -16 (since its the second solution with a negative sign) and -16 -8 is -24 /2 is -12
|2x+8| - 2 = 14
if |2x+8| >= 0
then
u use it as it is
2x + 8 - 2 = 14 ----------> x = 4
but if
|2x + 8| -2x = 14 +10 -------> x = 24/-2 x = -12

@@meryemtib948 and how would i know if |2x+8| >= 0 or |2x + 8|
Can anyone explain how the last two Questions are done
You need to move absolute value to one side of the equation and numbers to another.
Then it is the same as the first two.
