I'm practicing for my paper 1 as soon as I look at the question I pause the video then do it when I'm finished I resume it 😅

Hi

[@colephillips1505]

This was nice and easy good explanation aswell🔥

[@MisoThusini]

Refering to question 5.3 , is it correct if i factorized x^2 - 2x - 8 = 0 ( from 2x^2 - 4x - 16 = 0 ) into ( x - 4 )( x + 2 )

In 5.5 isn't x

[@user-ds1su2wv8k]

I was also thinking the same. I think he made a mistake, it's not the first time.
The answer is (-infinity ; 1)

[@etherealmercury3993]

That's exactly what I was think

[@etherealmercury3993]

So it would be
x E ( - ♾️ ; 1)

[@user-de4jj3db3k]

ohhh thank you.!❤

On question 6,how do we calculate b if we aren't given a

[@HlalunathiMashiyi]

Im also stuck on that but my teacher said somthing about simultaneous equations

[@its.nhlamulo]

use the formula y = a (x - x1)(x - x2). you use this only when they give a point and the two x intercepts. in q6 they give u a point D(1;8) but don't give you the values of the x intercepts. if they did give u, you'd substitute like this 8 = a (1 - x1)(1 - x2). x1 and x2 would be where your two different intercepts go. then you solve for a and substitute it back into formula to the equation of the actual graph then you get your b value from there
