Answer:
product of the roots= c/a
Step-by-step explanation:
The the two roots(α and β) of the quadratic equation ax²+bx+c=0 as given by shridharacharya formula are


now product of the roots
αβ=
×
use formula (a+b)(a-b)= a^2-b^2 and solve we get
αβ= c/a
therefore product of the roots= c/a
75.99 (tenths)
75.991 (hundredths)
75.9913 (thousandths)
About $12.91 because you divide 193.75 by 15 and you will get your answer
