Answer:
4 (4 x Superscript 4 Baseline minus 1)
Step-by-step explanation:
Completely Factored Polynomial: It's the polynomial that cannot be factored further. i.e. first polynomial cannot be factored further.
In second polynomial: y can be factored.
In third polynomial: 9 x squared can be further factored to 3 x and 3 x respectively.
In fourth polynomial: this is not factored i.e. it contains three (03) terms.
