Use inspection to solve the equation x² = 196, then select the correct solution below.
• {14}
• There are no real solutions
• {-14}
• {-14,14}
To solve the equation x² = 196 using inspection, we need to find the value(s) of x that satisfy the equation.
We can observe that 14² = 196. Therefore, x = 14 is a solution to the equation.
Similarly, we can observe that (-14)² = 196. Therefore, x = -14 is also a solution to the equation.
Therefore, the correct solution is {-14, 14}.
