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

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
