Question

Where do I have extra brackets in this quadratic equation? (see description)

Answer 1

I am writing a program in java to calculate the roots of a quadratic using the common quadratic equation. It all has to be one line (I'm trying to explain the QE to a computer).

I am unable to run my program because there is apparently a missing bracket.


This is my line:

((b*(-1))+sqrt(pow(b,2)-(4*a*c))/(2*a)



for those of you who don't know:
pow(1, 2) means raise the 1 by the power of the 2
sqrt() means square root what is in the brackets


Thanks

Answer 2

sorry, i didn't mean "extra brackets" I meant missing brackets (I think)

Answer 3

There would be another bracket after 4*a*c to close the very first bracket

Answer 4

((b*(-1))+sqrt(pow(b,2)-(4*a*c)))/(2*a)

Answer 5

you're right, thanks :)

Answer 6

now to test it :)

Answer 7

yep, it works. I've just got to sort the 12 errors which appeared after the brackets issue was fixed lol fml...
