So to find x you would then move 60 to the other side making it positive 60, then divide it by the 3 then square root both sides. So x ends up 5 +_ 2 root 5 ?
You would still need to factor out the number which is next to the a x^2 from all of the terms, you would just be left with some fractions that you need to deal with. If you have fractions in your quadratic though the method is still exactly the same. Hope this helps!
Because that's the rule for completing the square you always subtract the number inside the bracket squared that's just the rule for completing the square. Hope that helps. It's a process which is best to be memorised.

This was really helpful thanks
My pleasure - glad it helped! ⚡️
Thanks
My pleasure! 🙏
Ummmmm sorry i dont really get it but thr the video was good
The weird part is when the b,c doesn’t factorise by 3 like a what to do?

Man I need to go back to school.
Why did u subtract 25? Isn’t it add 25 since 5x5 equals a positive 25
