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.
2/7
use a absolute value to represent a negative number in the real world

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
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.
I really want to see x^3 to represent x to the power of 3 and x3 to represent the third element of the sequence (xn). Because in Calculus, we use x3, a5, etc. all the time. Anyway 3x^3 + x + 1 is a degree 3 (highest degree in the poly.) polynomial.
