Use the square root property to solve the equation. The equation has real number solutions.

[tex]\[ x^2 = 121 \][/tex]

[tex]\[ x = \square \][/tex]

(Simplify your answer, including any radicals. Use integers or fractions for any numbers in the expression. Use a comma to separate answers as needed.)



Answer :

To solve the equation [tex]\( x^2 = 121 \)[/tex] using the square root property, follow these steps:

1. Identify the original equation:
[tex]\[ x^2 = 121 \][/tex]

2. Use the square root property:
The square root property states that if [tex]\( x^2 = a \)[/tex], then [tex]\( x = \pm \sqrt{a} \)[/tex].

3. Apply the square root property to the equation:
[tex]\[ x = \pm \sqrt{121} \][/tex]

4. Simplify the square root:
The square root of [tex]\( 121 \)[/tex] is [tex]\( 11 \)[/tex], because [tex]\( 11 \times 11 = 121 \)[/tex].

5. So the equation becomes:
[tex]\[ x = \pm 11 \][/tex]

6. Express the solution as a set of positive and negative values:
[tex]\[ x = 11, -11 \][/tex]

Therefore, the solutions to the equation [tex]\( x^2 = 121 \)[/tex] are [tex]\( 11 \)[/tex] and [tex]\( -11 \)[/tex].
