2a

For each of the WeBWorK phrases below enter a T (true) if the phrase describes x correctly, and a F (false) otherwise.


1) -b+sqrt(b**2-(4*a*c)))/(2a) True or false

2) (-b+(sqrt(b**2-4*a*c)))/(2a) True or False

3) ((-b+sqrt(b**2-4*a*c))/(2a)) True or False


4) (-b+(sqrt(b**2-4*a*c))/(2a)) True or False

5) (-b+sqrt(b*b-(4*a*c)))/(2a) True or False

Answer 1

1. is missing a (

Answer 2

5 true
4 false it would take the sqrt(xxxx)/(2a) before adding -b

Answer 3

no in the question its like that
