Hey for the last two questions would it still be right if I had -3 on the end instead of 3 , or +2 on the end and + five in the first bracket

maths has always been stressful but after actually revising for once and using your videos everything is much easier to understand. thanks a lot for these videos man. quick question though, where would the foundation only questions end? since i'm not doing any higher papers.

@TheGCSEMathsTutor 2 года назад

Amazing news I’m so glad it working for you! So great to hear that everything is seeming easier and that you are gaining confidence! With my videos, if they are titles as “higher and foundation” or grade 5, these are topics that appear on both papers so the whole video is applicable to foundation as well as higher 😁🙏🏼

@ahyanbhol2500 2 года назад

how would you solve this equation 2x^2-5x+1

@sali__mk2245 2 года назад

2x^2 - x - 1 = 0 could be (2x-1)(x+1) so solutions could be x=0.5 and x= - 1 or am i wrong???

@GCSEALevelMaths Год назад

Careful it should be (2x+1)(x-1) so it’s -1/2 and 1

@alizasyeda2837 2 года назад

wait you know at @15:26 don't you have to do the opposite sign for -2.5 so it'll be 2.5?

@user-yz9xr6sc3o 2 года назад

No because 2x = -5 and youre trying to find x so you just divide -5 by 2 and get -2.5. He already did the opposite sign from +5 to -5 at the start.

23:29 , would it be wrong if I put the other number into the other bracket. So in this case, (3x+2) (x+5)

@drip5952 2 года назад

how should you decide which positive and negative sign go into which bracket? because regardless of which sign u put in it will give the same answer but if i don't know how to deduce which sign goes into which bracket i wont get the answer right so how do u deduce which sign goes into which bracket????????

Hello sir, I'm studying an IGCSE in maths and I 'm on the topic of Factorising Quadratics. Your videos really help but I really don't understand the bit where you explain why we must flip the signs, could you explain or just tell me why we flip signs when factorising Quadratics?
