Indeed, as long as the value you plug in does not make the denominator = 0, this is an effective way to check.

Just a small tip for those who are going through this now: Plug some value of x (e.g x= 17) into the original function, and calculate it using your calculator. Then plug the same value into the partial fraction that you found. If it matches, you're very likely to be correct (although there may be some exceptions).

bro the last question u did right we can take any other variables right instead of A i can say the C+ the other 2 fractions with A and B

Dread Gamer

17 and Ik you checked it

Jude Morris-Jones

bro's just cooked lol

Intuitive

What one is wrong? I just checked 15 & 16 to see and they're both correct.

Intuitive

My answers aren't wrong and my formula isn't wrong either. Could you elaborate?

Dread Gamer

check your answers again mate

Dread Gamer

bro all your answers for when the square is inside are wrong , your formula is also wrong

I found it in the GCE guide website of past papers. A=3, B=(-1), C=3

Again it took me a while to get through the video but I did it! Its really really helpful that you go through so many questions in the video. I'm gonna go tackle the worksheet now.

For our steps to make mathematical sense, we ourselves need to know whether the shit we're doing is valid or not lmao. I could be doing some random shit and it might as well just look valid to me lol

Intuitive

But if you send me a snap shot of the question on Instagram I'll do it for you :)

Intuitive

I will run through 2021 past papers soon. Do not fear

Ok thank you :)

Nasweer

Nah its all good, just wanted to point it out

Intuitive

Oh yeah my bad I can go back and do it if you want that question done. But it will be answered the same as all the others.

Nasweer

you forgot to include answers to question no 17 in the worksheet

Like he told us to do long division of the original fraction first. But your way's much simpler so I'll stick with that.

Intuitive

Not sure what you’re asking. But if you wanna divide something you can as long as it’s mathematically valid. Don’t be so focused on a method, just makes sure all your steps make mathematical sense. If they do you will get the right answer no matter what.
