Answer:

A. The rotation (x, y) -> (-x, -y)

Step-by-step explanation:

Let's call the point on the black triangle at point (-2, 1) "point A." The corresponding point to point A on the gray triangle is at point (2, -1). Let's call this point "point A'" or "point A prime." We can see that the x coordinate changed from -2 to 2. The y coordinate changed from 1 to -1. Thus, the answer is (x, y) -> (-x, -y) because the x changed from negative to positive and the y changed from positive to negative. I hope this helps :)

(X^2+y^2)^2 polynomial identify. Simplify
Alexxx [7]

Answer:

(x^{2}+ y^{2})^{2} =x^{4}+2x^{2}y^{2}+y^{4}

Step-by-step explanation:

(X^2+y^2)^2 polynomial identify. Simplify

i.e

(x^{2}+ y^{2})^{2} = ?

Solution:

We have the identity,

(A+B)^{2}=A^{2}+2AB+B^{2}

In the Question

A=x^{2}

B=y^{2}

Substituting in the identity we get

(x^{2}+ y^{2})^{2} =(x^{2})^{2}+2(x^{2})(y^{2})+(y^{2})^{2}

Also we have

(x^{a})^{b} =x^{a\times b}

(x^{2}+ y^{2})^{2} =x^{4}+2x^{2}y^{2}+y^{4}  Which is the required
