Which is the general form of the equation of the circle shown? x2 + y2 + 4x – 2y – 4 = 0 x2 + y2 + 4x – 2y + 2 = 0 x2 + y² – 4x
Lunna [17]
The equation of a circle with center at point (h, k) and radius of r units is given by
(x-h)^{2} +(y-k)^2=r^2

From the diagram, the center of the given circle is at points (-2, 1) and the radius is 3 units.

Therefore, the equation of the given by
\left(x-(-2)\right)^2+(y-1)^2=3^2 \\  \\ (x+2)^2+(y-1)^2=9 \\  \\ x^2+4x+4+y^2-2y+1=9 \\  \\ x^2+y^2+4x-2y+5-9=0 \\  \\ x^2+y^2+4x-2y-4=0

Factor Completely x^4-2x^2y^2+y^4
12345 [234]
<h3>Answer :</h3>

\bf (x+y)^2(x-y)^2

==============

<h3>Solving Steps:</h3>

===============

\rightarrow  \sf x^4-2x^2y^2+y^4

<u>breakdown</u>

\rightarrow  \sf x^4-x^2y^2-x^2y^2+y^4

<u>factor common term</u>

\rightarrow  \sf x^2(x^2-y^2)-y^2(x^2-y^2)

<u>collect in groups</u>

\rightarrow  \sf (x^2-y^2)(x^2-y^2)

<u>apply difference between two square method:</u> x² - y² = (x+ y)(x-y)

\rightarrow \sf (x+y)(x-y) (x+y)(x-y)

<u>simplify</u>

\rightarrow \sf (x+y)^2(x-y)^2
