Step-by-step explanation:

5d^2-145d+600

a=5. B=-145. c=600

d=b^2-4ac

d=21025-4(5)(600)

d=21025-12000

d=9025

x=(-b)+√d. or x=(-b)-√d

------------. -----------

2A. 2a

x=145+√9025, or. x=145-√9025

-----------------. ---------------

10 10

x=145+95. or. x= 145-95

----------. -----------

10. 10

x=240. or x=50

------ ----

10. 10

SO,X=24 OR X=5
