is the quadratic equation with the solutions -4 and -6
Given that -4 and -6 are solutions of a quadratic equation and asked to find out the quadratic equation
If "a" and "b" are the roots of the quadratic equation then,
sum of roots = a+b
product of roots = ab
There the required quadratic equation is 
Given that a= -4 and b= -6
sum of roots = a+b = -4 +(-6) = -10
product of roots = ab =( -4 )( -6 ) = 24
There the required quadratic equation is 
Hence, is the quadratic equation with the solutions -4 and -6

The only thing you need to do is 'cross-multiply'
Take the top of fraction 1 and multiply it to the bottom of fraction 2, and take the bottom of fraction 1 and multiply it to the top of fraction 2.
Then you will get a nice and easy equation to solve!
Charlie and sons- 75x100=7500+1000= $8500
home dreams- 80x100=8000+800= $8800

Answer:
$919.98
Step-by-step explanation:
To solve using a financial calculator do
N=8
I/Y=10
PMT=85
FV=1000
CMPT PV get 919.98
To do by hand find the present value of the interst payments
85*(1-(1/1.1)^8)
which is 453.4687
Find the present value of the final ballon payment
1000*(1/1.1)^8
which is 466.507
take the sum
466.507+453.4678= 919.98
