Equations & Inequalities in less than 20 minutes • A-Level Maths, Pure Year 1, Chapter 3 📚

Use this as quick revision, to summarise a playlist, and/or to check that you are ready to tackle exam questions. (Remember you can change playback speed on YouTube if you're in a rush!)

As this early on in this series, let me know what you'd like to see more of in future videos for chapter summaries!

At 18:53 aren’t you supposed to use the intersection symbol rather than the union symbol? Because we only want the intersecting area and not all possible areas of all equations combined(which is what union symbol means right)?

a good addition, sometimes the playlists can be long for a chapter that doesnt require too much attention if you've revised it before so itd be tedious

Given Two general equations for finding the value of "x" and "y"
1) ax + by = c
2) px + qy = c
Here (a, b, c, p, q are REAL NUMBERS)
Can we write
(ax+bx = px+qx)
( substituting the value of "c"and "c" is REAL NUMBERS like

Is it correct or not
Please help with example 🙏🙏

Hello Mr Bicen,
May I ask that we please have these videos in a playlist, please ? - one for Pure 1, another for Statistics 1, etc. Thank you

if it was kx^2 - 4x - (k+3)

would the value for c be -k-3? as i would have expanded the brackets to get this or would it still remain as k+3
