Factor the following polynomial completely -x2 y2 + x4 + 4y2 -4x2

ANSWER:

The factors of

SOLUTION:

Given, polynomial is  

This is an polynomial in two variables with degree 4

So the given polynomial will have 4 factors.

We need to factorise the given polynomial.

Now,

[writing terms with y as one part and remaining as another part]\

Taking the common terms out of brackets.

Taking as common

Hence the factors  of

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
