If you are a female who is good at Math and/or Physics what sign are you? Most females aren't so I am interested in those that are.

Do you mean quadratic equations such as: x^2+2xh+h^2 = (x+h)^2? Cause this is like simple equations we learn in first high school year in my country :O Using bhaskara formula and such to solve it... Congrats on your qualification tho.

For some reason I just seemed to have some kind of a phobia about QEs (apparently it's not unusual): I am even thinking of hiring a private tutor to help me crack them.

nice 🙂But this is like two ways to solve the same type of thing kinda, just you have to see wich formula is applicable to wich equation. Some you can solve both with "identity" and this other formula, while more "complicated" ones can be solved only with this formula... Anyways i should have copied the generic way ax^2+bx+c=0 in my example over there hehe but nice you took the time to correct me

What you wrote is an Identity.
Equations (to be solved) are like this one: x^2+2xh+h^2 = 0.
Blahblahbla = 0.
Both Identity and Equation are discussed at school. Bascically Identities are used to solve equations, if applicable.
In the following example they use another Identity: x^2 - a^2 = (x-a)(x+a).
