Maths question on making the subject

  • #1
Hi.

A = 1/2 B (C - D) ^2

And I wanted to make B the subject

I have done:

2 x B = (C - D) ^ 2 / A

B = ( (C - D ^ 2) / A) / 2

Is this correct or not? And if not could you please amend it to make B the subject?

These are not the actual variables in the question by the way.


Also, how would I make D the subject in:

A = 1/2 B (C - D) ^2

Any help is appreciated. Thanks.

Hi questions_uk! :smile:

(try using the X2 tag just above the Reply box :wink:)
A = 1/2 B (C - D) ^2
Do you mean A = B(C - D)2/2,

or A = (C - D)2/2B ? :confused:

When someone asks for clarification, do NOT just repeat the original post!

Please answer the question! Is that
A= 1/(2B(C-D)^2) or A= (1/2)B(C-D)^2 ?
