Need Maths Help To Get Into College?

Question

On college induction day i was given a question for homework and I can't figure out how to do it :(

The question is:

V(squared) = U(squared)-2ac

Make "a" the subject.

Can anyone help and show me how to do it ?

Answer 1

V² = U² - 2ac;

Subtract U² from both sides:

V² - U² = -2ac

Divide both sides by -1:

U² - V² = 2ac

Divide both sides by 2c:

(U² - V²)/2c = a
