Answer:
151200 ways
Step-by-step explanation:
Well assuming the numbers go from 0 to 9
we have
_ _ _ _ _ _ six spaces
in the first one can go one of the ten so the first one has 10 options
10*_ _ _ _ _
the second one has 9 options because we have used one alredy
and so on
10*9*8*7*6*5=151200
Given:
The function is:

To find:
The zeroes of the given function by using the Method of Completing the square.
Solution:
We have,

It can be written as:

By Method of Completing the square add and subtract square of half of coefficient of x in the parenthesis.


![[\because (a+b)^2=a^2+2ab+b^2]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%28a%2Bb%29%5E2%3Da%5E2%2B2ab%2Bb%5E2%5D)


For zeroes, F(x)=0.




Taking square root on both sides, we get


and 
and 
Therefore, the zeroes of the given function are -0.45 and -5.55.
