What he/she said is correct
Xy is the GCF of these expressions
Answer:
The number of roots for equation
is 4 .
Step-by-step explanation:
Here, the given function polynomial is :

The Fundamental Theorem of Algebra says that a polynomial of degree n will have exactly n roots (counting multiplicity).
Now here, the degree if the polynomial is 4 (highest power of variable x).
So, according to the Fundamental Theorem, the given polynomial can have AT MOST 4 roots, counting Multiplicity.
Hence, the number of roots for equation
is 4 .
A line means divided by
So basically if it was 1/2, then it would be 1 divided by 2.
P. S. 1 divided by 2 is not the answer I'm just explaining what a line is
