Answer 2

Answer:

Step-by-step explanation:

x^2+400x-1600=0

a=1 b= 400 c=1600

-b±√b^2-4ac/2a

= -400±√400×400-4×1×1600/2×1

= -400±√160000-6400/2

= -400±√153600/2

=-400± 391.92/2 (approx)

For positive (+)

-400+391.92/2

= 8.08/2

=4.04

For negative (-)

-400-391.92/2

= -791.92/2

= 395.96

Therefore

x=4.04 or 395.96
