Answer:


x=0.00009028, x=-2.999909725

Explanation:

Use the quadratic formula:


x=(-b \pm √(b^2-4ac) )/(2a)

when
ax^2+bx+c=0

Therefore, for
144000x^2+431974x-39=0

a = 144,000 b = 431,974 and c = -39

Substituting this data into the quadratic formula:


x=(-431974 \pm √(431974^2-4(144000)(-39)) )/(2(144000))


x=0.00009028, x=-2.999909725
