Solving Quadratic Equations by Factorising

[@Great_WesternTVFan]

My maths teacher back in school did not mention about using factor trees for the variable next to the algebraic value, hence I struggled. But you giving me this idea made my life so much easier, I really hope I get a solid grade when I do the higher re sit GCSE maths in 2024 summer.

The only quadratic equation video I actually understand!

[@ShakeelAhmad-nx7bw]

This video is really helpful. Thanks a lot

For the answers where one is positive and one is negative, are they interchangeable with their positive/negative counter parts? For example if the answer was -2 and 10 would -10 and 2 still be a viable answer?

Thank you so much I have a maths test tomorrow first thing and I’m not looking forward to it 😭🙏

THANKS BRO

wouldnt at 14:03, for that last question be the difference of 2 squares ? 9 is a square number

[@SSSPrince]

9g is different from 9

[@paulastreet4557]

At 11:21 the third example in that part, I was expecting there to be only one bracket for c^2 - 36=0 .... just rewatched - now I get it - it's two squares, one of them being 36! Phew.

[@ash-wf7vx]

so if it’s a square number I should always do two brackets? Only if it’s a squared number right

[@paulastreet4557]

For the equation 3) g^2 - 8g - 20 =0 how do I know which of the factors is negative and which is positive? Would I have to try it out by substitution? Or is there a way to know?

[@katiebeale7275]

i think usually the bigger number is positive but not for every question.

[@yuv4u]

very thanks for that

[@originalasmruvu8423]

2 and 10 make 8!?

[@donkeydonkey1852]

Its because it has a minus question

[@donkeydonkey1852]

In it*

[@XPSnova]

I could revise it

[@danilomoviescenter5787]

Its good.....

[@honeydeans3897]

This is my homework…
