Question

Factor the following polynomial completely.
-x^2y^2 + x^4 + 4y^2 - 4x^2

Answer 1

answers
(x - 2)(x - 2)(x + y)(x - y)
(x + 2)(x + 2)(x + y)(x - y)
(x + 2)(x - 2)(x + y)(x - y)

Answer 2

third one i guess

Answer 3

u guess?

Answer 4

It is the third one because if you factor by grouping, you get (x^2 - 4)(x^2 - y^2) which can factor out to (x + 2)(x - 2)(x + y)(x - y)

Answer 5

ok thank you @Calcmathlete

Answer 6

You're wlcome

Answer 7

yep.....see the last two terms (x+y)(x-y) it gives x2-y2
but from the question both have reverse sign.....u have to multiply with a negative number....like -4
lazy 2 solve that question
