I don't know specifically what the sum and product of an equation is but
factor using quadratic formula
if you have an equation in ax^2+bx+c=0 then you can solve for x using

or

so input
a=1
b=7
c=2



=aprox -0.2984378812836

Answer:
(a) $60 | (b) $660
Step-by-step explanation:
We can use the simple interest formula for this:

<em>I = interest amount</em>
<em>P = principal amount</em>
<em>r = interest rate (decimal form)</em>
<em>t = time (years)</em>
<em />
First, change 5% into its decimal form:
5% ->
-> 0.05
Next, plug in the values into the equation:


<em>The interest earned is $60. To find the total balance, just add the $600 back.</em>

The total interest earned is $60 and the total is $660.
