Factor completely 5x4 − 80. 5(x2 − 4)(x2 + 4)

5(x − 2)(x + 2)(x + 2)(x + 2)

5(x − 2)(x + 2)(x2 − 4)

5(x − 2)(x + 2)(x2 + 4)

Step-by-step explanation:

The expression given is:

Difference of two squares:

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
