Lol the first question is wrong

3 times 2=6, not 15. Please make sure not to make this mistake again.

Can you do algebraic fractions

He kept talking about how this rule is fine but he prefers doing it another way, then proceeds to do two different exercises but the same way…?

Thank you so much, this helped a bunch.

can you please do a video on quadratic equations for year 9. I'm am really stuck and would love your help @tecmath

The first question is wrong.

(x+2)(x+3)

=x^2 + 3x +2x +6

=x^2 + 5x + 6

But I don't know how you got

=x^2 +5x + 15

Where did the 15 come from the equation.

where is the following video??

where is the following video??

he said gday that means he is aussie

uhh wasn't the first questions answer wrong????

Dear all, does anyone know what would be the answer to: Y=(200/x)+400x. ? I appreciate any help. thanks

3*2π=

its way too basic

It would be really helpful if these videos were given numbers in a series please, as I am never sure which one is next! Thanks.

what about RATIONAL EXPRESSIONS?😊

DAMN ITS SO DIFFICULT TO UNDERSTAND😭

So what does, please, a 'Quadratic Equation' actually mean?!

This now is just getting sooooooooo difficult ;-(

2×3=6

you are thegood teacher and a life saver thank you soooooo much now i dont have to worry about math stuff cause you taught the easy way and more understandable and gives us shortcuts.

Which year would you learn this? (approx)

So after this video i dont think im going to have a mental break down because of my maths test tomorrow, cheers

what's 3×2 15

he ment to add out 2 and 3 to get 5 with an x

Thank

Don't you also use the FOIL concept? First, Outer, Inner, and Last to factor these?

great video! I never understood quadratic equations until watching this video. excellent and easy to comprehend examples! thank you 🙂

3×2 is 6 not 15

Very good

It was a silly mistake ! and I'm pretty sure he knows the answer of 3 times 2

1:20 you say: "3 times 2 is 15". Well i'll admit that i'm not good in math and stuff, but though i'm pretty sure that's wrong.

now it is

Great video mate
