Question

find the solution for the equation using a table
$x^2 + 18x + 81 = 0$

select the correct choice and, if necessary, fill in the answer box to complete your choice

a. the solution(s) is/are $x = \square$
(simplify your answer. use a comma to separate answers as needed.)

b. the equation has no solution

Explanation:

Step1: Factor the quadratic

$x^2 + 18x + 81 = (x+9)^2$

Step2: Set factor equal to 0

$(x+9)^2 = 0$

Step3: Solve for x

$x + 9 = 0 \implies x = -9$

Answer:

A. The solution(s) is/are x = -9
