Answer:

x=1/15 y = -4 1/3

Step-by-step explanation:

First combine like terms.

-3y = 13

y= -13/3

y= -4 1/3

Substitute for y in next equation

-4 1/3 = 5x - 4

5x = 4 1/3 - 4

5x = 1/3

x = 1/3 divided by 5

Since fractions can't be divided, multiply by the inverse

x = 1/3 times 1/5 = 1/15

Factor the following polynomial complete -x^2y^2+x^4+4y^2-4x^2

Annette [7]

Answer:

$(x+2)(x-2)(x+y)(x-y)$

Step-by-step explanation:

First, see if you can group the terms. I will first put this in LaTeX to make it easier to understand. We have $(-x^2y^2+x^4)+(4y^2-4x^2)$ , and we can factor a $-x^2$ out of the first group, and a $4$ out of the other group, to get $-x^2(y^2-x^2)+4(y^2-x^2).$ Let's multiply everything by -1 now to ge t $x^2(x^2-y^2)-4(x^2-y^2)=(x^2-4)(x^2-y^2).$ Multiplying all this does not change it, because -1^2=1.

Because a^2-b^2=(a+b)(a-b), we get out final answer as $(x+2)(x-2)(x+y)(x-y)$ . $\blacksquare$
