The problem why I struggle with algebra is because I'm just blindly following steps. I don't know why I do what I do in algebra because I just follow a method. That's what makes learning algebra hard and forgettable for me.

I know this comment is two years old but I have been there and I want to advise anyone else who is struggling that sheer repetition was key for me to 'get' this. I must have watched about twenty videos several times on the subject. I had to blindly follow the steps at first and then with repeated practice it began to sink in and I started to spot patterns and develop an intuition about what to do. Now I can do them and the example in the video was no problem for me. Good luck.

This is exactly what I’m looking for

Great video! Thanks for the help! 🙏🏻

Simon Deacon saving lives out here bless up

what about if the 1 on the right hand side of the equation is a bigger number? i multiplied by the brackets but it leaves me with huge numbers which are difficult to factorise

You can move the x to the left because x^2 minus 2x^2 is -1x^2 but because ou square it, its still positive x^2

This was so helpful thanks!

Hi Simon, can you help? I was able to follow everything except that you got rid of one pair of the brackets (one each of the two terms) in the denominator when you made it into one fraction? Why did they become only (2x-3) (x+1) instead of the two pairs of these? And how come they aren't multiplied out in the denominator? Thank you

Hi - the idea of making both individual fractions to have the same denominator, is so that I can combine them into one fraction. It’s the same as adding say: 1/3 + 1/4 The common denominator is 12, so I can rewrite as 4/12 + 3/12 Which then combines to 7/12. Hope that’s OK and all best S

With the question you've got 1/1 on the right hand side so you can cross multiply to: 1 x (xsquared + 9x - 12) = 1 x (2x - 3)(x + 1) Hope that's OK and all best S

wait when you moved the +9x over to the -x, wouldn't moving +9x make it a -9x? then because your subtracting it wouldn't it be -x subtract -9x becoming -x + 9x?

@3minutemaths

Hi - Great question and appreciate the comment. It's not -x - -9x , which would be -x + 9x as you mentioned. Instead, (forget the other terms): +9x = -x So, I need to get the +9x on the right hand side .... this is done by -9x to both sides of the equals sign, and 'balances' the equation around the equals sign (think of it like a playground seesaw) -9x + 9x = -x - 9x On the left side I get 0 (nothing), on the right side I get -10x 0 = -10x Hope that helps and all best S

Then I bring over the 9x on the left hand, this is now a negative as I’m subtracting 9x from both sides. So -x -9x = -10x Same with the -12 on the left side. It becomes +12 when taken to the right.
