im so happy you started uploading again, can you please keep uploading for year 1 pure 1 because now im starting with chapter 3 and to be honest you're the best teacher for me. keep it up man 🖤
00:03 Understanding the discriminant in quadratic functions. 01:36 Understanding the discriminant in quadratic functions. 03:13 Discriminant less than 0 implies no real roots 04:38 Solving a linear inequality in k 06:12 Finding the values of a, b, and c for a quadratic equation. 07:40 Understanding the relationship between a straight line and a curve graphically. 08:55 To determine no solutions between line and curve, discriminant must be negative 10:34 Analysis of discriminant inequality in quadratic equations.
When you ÷ with inequalities you need to switch the signs to make the equation true. For example: 3>2 right? However if you ÷1 on both sides you're left with -3 > -2 which isn't correct so you need to switch the inequality sign when you divide
it’s like having the smart but cool student in your class teaching you

THE FACT YOU UPLOADED THIS 3 WEEKS AGO AND I LITERALLY NEEDED THIS SOO BADLY RN, THANK YOU OH MY GOD
at 7:35 the answer is actually only S = 4 because in the question it says S is a positive constant
wouldn’t it be 45s and not 4s?

Thank you so much , I studied 2.1-2.4 from your videos this weekend and I left 2.5 for today and I came to find this video . Thank you !
More AS topics please and I applaud how you guide through with the textbook chapters aswell
just started as level maths and your helping sooo much
Where is the question at 7:45 from
sir do you drive an m140i
Ehy do you set them = to eacvhother if they dtont intersect or touch??
that was brilliant, explanation was spot on
bro you are a lifesaver👌
Perfect timing i just did this today
Does that mean you’re going to make more AS Maths now?
that fade tho
keep uploading, this was so good, keep upppppp
Why did you flip the inequality at 5:20
When you ÷ with inequalities you need to switch the signs to make the equation true. For example:
3>2 right?
However if you ÷1 on both sides you're left with
-3 > -2 which isn't correct so you need to switch the inequality sign when you divide
I do not understand why for question 3 you make the equations equal each other.
Same since they dont intersect
@@khattakjarir3399 they are both y so they are equal to each other
@@user-su6js9po4l oh shi yh ahaha thanks
@@khattakjarir3399 np lmao
Please do more !!
pleaseee upload 2.6vmodelling Quadratics
Thank you!!!
Thank you for this, my P1 exam is in a week or so and it helped massively!
legend!
Yo this is bussin #teampushpa
chapter 3?
plsssssssssssssssssss
my guy
can you come and teach at my school please
