To show physically a factorization of a quadratic I would use algebra tiles. First the upper left would be the number of squares I had put in a rectangular array.
The lower left would be the number (constant) I had in a rectangular array. The deminsions of the squares would be my variable and the deminsions of the small square would be my constants.

You could represent it as 4/8.
The same as you would a rational number. Its distance from zero will represent the number, whether it is rational or irrational.

use a absolute value to represent a negative number in the real world
A byte represented of 8 bits
The zeros of a polynomial represent the points at which the graph crosses (or touches) the x-axis.
A quadratic can be used to represent many different things, such as parabolic/satellite dishes and the flight of ballistic projectiles.
If a polynomial expression is derived from a word problem it has the same meaning as the word problem. Polynomial expressions that represent scientific laws have the specific meaning of that law.
b is the negative sum of the roots of the equation

That's not a prime factorization because 9 isn't prime, but it does represent the number 126.
A quadratic expression is an expression which is written in the form ax2+bx+c, where a, b, and c represent constants, x represents a variable, and a is not equal to 0.
The quadratic formula is used today to find the solutions to quadratic equations, which are equations of the form ax^2 + bx + c = 0. By using the quadratic formula, we can determine the values of x that satisfy the quadratic equation and represent the points where the graph of the equation intersects the x-axis.
Polynomial
In quadratic equations, the solutions represent the values of the variable that make the equation true, typically where the graph of the quadratic function intersects the x-axis. These solutions can be real or complex numbers, depending on the discriminant (the part of the quadratic formula under the square root). Real solutions indicate points where the function crosses the x-axis, while complex solutions indicate that the graph does not intersect the x-axis. Overall, the solutions provide insight into the behavior and characteristics of the quadratic function.
To find the zeros of the polynomial from the given graph, identify the points where the graph intersects the x-axis. These intersection points represent the values of x for which the polynomial equals zero. If the graph crosses the x-axis at specific points, those x-values are the zeros of the polynomial. If the graph merely touches the x-axis without crossing, those points indicate repeated zeros.
If the highest exponent of independent variable(say x) is 2 and the highest exponent of dependent variable(say y) is 1 and x and y are not multiplied, then the function is quadratic. For example: 3x-y+x2= 2y-5x+7 represents a quadratic function but y= xy+x2+5 doesn't represent a quadratic function.
