Thank you very much Zeeshan for your upload, I went looking for help with factoring quartics as I was struggling with the challenge in section 1.3 of the Pearson book which I am currently self teaching and xame across your video which was very helpful with this - substituting x^2 for y makes a lot of sense in this context.
P_S_ At 17:00 I believe you left (x^2-y^2) which could be factorised further as it is another difference of two squares? So final answer (x^2+y^2)(x+y)(x-y)?

in the example (g), why can't we divide by 2 and which will ends up giving (x+5)(x-5) as final answer ???

for e does anyone know if you must always reduce the quartic or whatever it maybe if a multiple of 2 down to a quadratic?

hi thanks for the vid, for question e, at the end before factorising, does it matter which number in the bracket goes before/first? because putting 6y before 8y instead of 8y then 6y changes the factorisation as they're split off differently so I got a slightly different answer. Just wanted to know thx

16:35 I think you missed a point! here we can continue factorising even more. Like instead of keeping (X2 -Y2)(X2+Y2) we can do (X+Y)(X-Y)(X2+Y2) ...I HOPE you read this comment and get what I meant and reply as soon as possible .SIR!! 😁😁
