Question

What are the solutions to the equation x² = 169? Choose all answers that are correct. A. 13 B. –13 C. 84.5 D. –84.5

Answer 1

$x^{2} = 169$

First, we need to take the square root of each side. 
$x = \pm \sqrt169$

Second, we now have to find the square root of 169 to solve this. Since 13 × 13 = 169, the square root of 169 is 13. The plus-minus symbol means in this case, the solution can be -13 and positive 13. To answer your question, option A) 13, and B) -13 are the solutions to the equation.
$x = \pm 13$

Answer: $\pm13$

Answer 2

Answer:

The answers are A. 13, and B. -13.
