4 0

x²+y²-2x-6y-5=0

x²-2x+y²-6y=5

x²-2x+1+y²-6y+9=5+1+9

(x-1)²+(y-3)²=15

(x-1)²+(y-3)²=(V15)²

-> centre of the circle: C(-1,-3)

-> radius of the circle: V15

Find the solution set. (x+7)(x+7)=0
levacccp [35]

For this case we must find the solution of the following expression:

(x + 7) (x + 7) = 0

If we isolate a term and we equate to zero, we have:

x + 7 = 0

Subtracting 7 on both sides of the equation we have:

x + 7-7 = 0-7\\x = -7

Thus, the solution of the expression is given by:

x = -7

ANswer:

x = -7
