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:

$x = -7$
