    Man your videos are always super easy to follow! Revising physics and some algebra for uni and I stumbled upon this.
    I always wonder what math is used for... especially this... what can be substitution used for?
    Like in real life, could it be used for something? Figuring out something? Physics? Engineering? Tougher equations?
    It bothered me that in high school we just learned things to learn things but never really got an answer what these equations could be used for or what's the point of learning them.
    Could you give me an answer good sir?

    • @3minutemaths
      @3minutemaths  3 роки тому

      Hi - thanks for this and completely appreciate your comment. Personally I see maths through Engineering due to my previous career ... for me, most maths was very real. I could see how important it was to understand the effects of mass, gravity, momentum, force, friction, heat etc - maths is really just the language we use to describe these things. High School maths tends to provide a basic foundation; depending on your career, it might become less or more important. Either way it's great that you're asking the questions 🙂

    How would you determine x if when you factorise it, it is like this: 5x(x+4) for example. Great video though!

    • @3minutemaths
      @3minutemaths  5 років тому +1

      Hi - you can only work out X if the equation is equal to something. In your example, if you made it equal to 3, you’d get:
      5x(x + 4) = 3
      Expand to
      5xsquared + 20x = 3
      Or
      5xsquared + 20x - 3 = 0
      You could then use the quadratic formula to find out if x has any values.
      Hope this helps and all best S
