For the polynomial x2 + 10x + 25,
a =
b = .

The values are a=1 b=10 c=25 and solving the expression we get x=-5

Explanation:

Given equation;

Solution:

The above equation can be written as

This equation is in the form of

is the general quadratic equation.

Comparing the above equation we get  

A=1, B=10 and C=25

To find value of “x” we use the formula as  

=

Substitute the values of a, b and c in the above equation we get

=

=

=

=

=-5

Results:

Thus the values are A=1, B=10, C=25 and X=-5

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies

answer: 3.26019516
