Therefore the total would be £106.15.
Step-by-step explanation:
(-1,0),m=2
(1-7),m=12
m=-4,(-1,-4)
Using Vieta's Theorem, it is found that c = 72.
<h3>What is the Vieta Theorem?</h3>
- Suppose we have a quadratic equation, in the following format:

The Theorem states that:


In this problem, the polynomial is:

Hence the coefficients are
.
Since the difference of the solutions is 1, we have that:


Then, from the first equation of the Theorem:





Now, from the second equation:
