Answer: 
Step-by-step explanation:
Given: u and v be are the solutions of 
Let 
is the quadratic equation and u and v are the zeroes/solutions then
Sum of zeroes; 
Product of zeroes; 
Comparing to
we get a= 3 , b= 5 and c = 7
Now we have to find
adding and subtracting 2uv in numerator we get
Substituting the values from (i) and (ii) we get
Hence, the value of 
is
Answer:
The annual growth rate between 1985 and 2005 is 0.95%
The value of the house in the year 2010 is $152,018
Step-by-step explanation:
Let the annual growth rate = r
Value of the house in year 1985 = $120,000
Value of the house in year 2005 = $145,000
Time (t) = 2005 - 1985
= 20 years
A = P (1 + r)^t
145000 = 120000 (1 + r) ^20
(1 +r)^20 = 145000 / 120000
(1 +r)^20= 1.2083
(1 +r)^20= (1.2083)^1/20
(1 +r)^20= 1.0095
r = 1.0095 - 1
r = 0.0095
r% = 0.0095 x 100
= 0.95%
Value of the house in year 2010
=145000(1 + r)^5
=145000 (1 + 0.0095)^5
= 145000 x 1.0484
=$152,018
