Actually about to have a mental breakdown over my maths assignment
Why, in the equation;
-b +or- thesquarerootof b^2-4ac/2a
If b is a negative number you only put it down as a negative once ?!?!?!
For instance if it was -7 you would write
-(-7)+ thesquarerootof 7^2-4ac
Why does it not have to be negative the second time around?! Silly maths!!!
