i used your videos religiously when i took a level further maths, now i am in my third year of my degree and i am back to dusting off these techniques for my final exam before i graduate! thanks for the help for so many years!

[ekensington]

your videos have saved my mathematical life

[UCIE-otei]

There’s one aspect of these that had been driving me nuts for a while now and you’ve just explained it clearly for me here. Thanks 🤝

[Calmingdown]

I want to say thanks for the help provided in this and the previous video. They have both been very helpful towards revision purposes. Thank you again

[madhazel]

Thank you so much!! You don't know how much this helped! It cleared up a lot of my questions and problems :) So again, thank you for the tutorial!

Um, regarding your 'calculation method' of squaring both sides you use here...
would it still technically work for values like l -x + 1 l where the x is negative?
Also, say you have the scenario where l x + 2 l > 5 l x - 3 l would you still be able to apply the squaring method to this by (x + 2)^2 > 5(x - 3)^2 or is this impossible?

Sorry for asking so many questions, and thanks! :)

At 10:31, what if you moved the 4x^2-12x+9 to the right? Would the signs change? Cuz if not it would be -3x^2-6x<0

[darrylpinto]

Do these examples apply when it is greater than or equal to mod function ie clinical term slack inequalities?

[aimenkhalid]

At 6:44 why was it an 'or' situation and i still dont get how x is greater than 6

[icecreamcrafter]

Thanks, Sir. This is precisely helpful for my IGCSE maths.

[sweeterman]

To do the calculation method do the two coefficients of the x's have to be positive or the numbers?

[deloarhossain]

Could you please mention the tools (i.e whiteboard and the marker) you used to make this video

[kavyanegi]

Please make more calculus videos. Or anything related to pre-calc/calc.

[jordanjackson]

would the sketching method also work for | x +2 | = 4 for example, and just drawing in the line x=4?

[zatak]

Hello Sir, which software do you use to demonstrate your workings?

[thapelopotloane]

what would you do for Ix-2I>3I2x+1I because I get negative values which is not possible of absolute value

[dicksonmuntete]

your teaching covers all angles, Thanx
