Answer:
The product of the model is [tex]x^2-9x+25[/tex]
Step-by-step explanation:
Given the expression (x-5) and (x-4)
The product of the two factors can be expressed as follows
[tex]= (x-5) (x-4)\\=x(x-4)-5(x-5)\\[/tex]
Opening brackets we have
[tex]=x^2-4x-5x+25[/tex]
Collecting like terms we have
[tex]=x^2-9x+25[/tex]
