Answer:
<em>The zeros of the polynomial are -1 and 5</em>
Step-by-step explanation:
<u>Quadratic Equation Solving</u>
The standard representation of a quadratic equation is:
where a,b, and c are constants.
Solving with the quadratic formula:
We have the following equation to solve:
Before attempting to solve it, we must simplify the equation.
Collecting like terms and reordering:
Here: a=1, b=-4, c=-5
The discriminant of this quadratic equation is:
Given d is positive, the equation has two roots, and since d is a perfect square, both roots are rational.
Applying the formula:
Dividing by 2:
Separating both roots:
x = 2 + 3 = 5
x = 2 - 3 = -1
The zeros of the polynomial are -1 and 5
Answer:
the future value is £15,243.56
Step-by-step explanation:
The computation of the future value is shown below:
As we know that
Future value = Present value × (1 + rate of interest)^number of years
= £7400 × (1 + 0.128)^6
= £15,243.56
Hence, the future value is £15,243.56
Answer:
