Exploring the Quadratic Expression: (m2)x²  (5+m)x + 16
This article will delve into the quadratic expression (m2)x²  (5+m)x + 16 and discuss its properties, potential applications, and how to analyze it.
Understanding the Expression
The given expression is a quadratic equation in the variable x, with m as a parameter. This means that the value of m will influence the behaviour of the quadratic expression. We can observe the following key features:
 Leading Coefficient: (m2) determines the shape of the parabola representing the expression. If (m2) is positive, the parabola opens upwards, and if it's negative, it opens downwards.
 Linear Coefficient: (5+m) affects the position of the vertex and the axis of symmetry.
 Constant Term: 16 is the yintercept of the parabola.
Analyzing the Expression
To gain a deeper understanding of this expression, we can investigate several aspects:

Roots or Solutions: Finding the roots or solutions (values of x for which the expression equals zero) involves solving the quadratic equation. We can use the quadratic formula for this:
x = [b ± √(b²  4ac)] / 2a
where a = (m2), b = (5+m), and c = 16.

Vertex: The vertex of the parabola is the point where the expression reaches its maximum or minimum value. Its coordinates can be determined using:
xcoordinate of vertex = b / 2a
ycoordinate of vertex = f(b / 2a)
where f(x) represents the quadratic expression.

Discriminant: The discriminant (b²  4ac) provides insights into the nature of the roots:
 If the discriminant is positive, there are two distinct real roots.
 If the discriminant is zero, there is one repeated real root.
 If the discriminant is negative, there are two complex roots.
Applications
This type of quadratic expression can find applications in various fields, such as:
 Physics: Modelling projectile motion or oscillations.
 Engineering: Designing curves for roads or bridges.
 Economics: Analyzing profit functions or supply and demand curves.
