Hi, I’ve just finished my GCSEs and am strong in Maths so I hope this is right and helps you.

+3b
(x/a)^2=3b+2c

Square root
(x/a)=rt 3b+2c

Multiply by a
x=a(rt 3b+2c)

Also there is a free app called Photomath which solves maths questions for you. Hope this helps!

+3b on both sides to get: x/a^2 = 2c+3b
then times both sides by a^2 to get x = a^2(2c+3b)

hope that helps

Why are you telling me what to do and just ordering it in such a rude manner? All you needed to do was reply and say that it’s a rule, rather than telling me what to do and capitalising it — don’t treat people like they’re idiots.

Since when was this a rule in TSR? I created a forum when I needed help with a science question where I got helpful answers.

And why are you only telling this to me and not the other poster?
