[@johnkhan9579]

I really lovc these videos. You explain the steps so well, I was just wondering about the answers (timestamp 6:00), where the question asks for 3 significant figures, as opposed to rounded. So, the solutions would be 4.60 and 1.58. Or maybe I am wrong.

[@musa2908]

its -0.941 for the second value

[@Sami-vd3co]

great video, please correct me if im wrong but i believe the answer to question 2 is wrong 3x^2 - 11x - 13 = 0 x = 4.61 or -0.91 ( NOT -1.59 )

How is the answer for number 2 on the quadratics equation bit -1.59 it’s coming up on my calculator as -0.94

Hey, one thing im a bit unsure of is am i allowed to just type in the quadratic into my calculator to solve rarther than using the quadratic formula?

[@mallikaamarasekara7844]

Sir how did you get the negative answer for the 2nd question?please explain it. 6:38

[@Deadman2DX]

I doubt he would reply but to answer that you probs forgot the brackets around -11 which means you did 11 squared; so 11 times 11 then made it negative - rather than -11 times -11 which would change your whole answer 👍

[@tejeshvararunkumar9411]

How do you make your own quadratic equation when it gives you the values for the roots and the turning point? I can't find the answer for this anywhere

[@TheGCSEMathsTutor]

If you were given the roots - say x=3 and x=-2 then you know the factorised form would be (x-3)(x+2)=0 expand and simplify and there you go 😁👍🏼

Hi Sir. Thankyou very much for this amazing video. Very well explained, great job! However, I was wondering if you could make a video re. examples of the Quadratic formula where you do the working out to show the answer. I have noticed that no tutors explain as well as you do. And, rectangle word problems with area and quadratic equations is something I'm struggling with at the moment. For example, A rectangular field is 15m longer than it is wide. The area of the field is 800m². Work out the length of the field. Give your answer to 1 decimal place. If it is possible, would you be able to help me out with this? Thank you Sir for your time. 🙂🙏👍

[@TheGCSEMathsTutor]

Aaaah yes forming and solving quadratic equations would certainly be a good one! I’ve just added it to the list for you 😁 what do you mean by the first one? Where you show the working out, do you mean doing the quadratic formula without a calculator and leaving it in surd form? 😁🙏🏼
