Edexcel AS Level Maths : 2.5 The Discriminant

[@onlineenth4454]

it’s like having the smart but cool student in your class teaching you

[@playbouicarti]

at 7:35 the answer is actually only S = 4 because in the question it says S is a positive constant

[@TheEverythingClip]

wouldn’t it be 45s and not 4s?

Thank you for this, my P1 exam is in a week or so and it helped massively!

[@sha3tyb0i41]

Why did you flip the inequality at 5:20

[@aaliyabi5468]

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

[@kutiepatutie]

Thank you!!!

[@caffeinatedstudent7187]

I do not understand why for question 3 you make the equations equal each other.

[@khattakjarir3399]

Same since they dont intersect

[@user-su6js9po4l]

@@khattakjarir3399 they are both y so they are equal to each other
