Like radicals are radicals that have the same root number AND radicand (expression under the root).
And there ya have it!
Happy studying.

Hello :
<span>x²+2x+y²−4y+z²−8z=60
(x²+2x) + (y² - 4y) +(z² - 8z) = 60
(x²+2x+1) -1 +(y² - 4y +4 ) - 4 +( z² - 8z+16) -16 = 60
(x+1)² +(y-2)² +(z - 4)² = 9²
</span><span>the center is the point : A(-1, 2 , 4)
and radius : 9</span>
