Final answer:
To solve the equation x² = 26, take the square root of both sides, which results in two solutions, x = ± √26, indicating both positive and negative square roots. Therefore correct option is A
Step-by-step explanation:
The equation given is x² = 26. To solve this, take the square root of both sides. Remember that when you take the square root of a variable squared, there are always two possible solutions, a positive and a negative.
Therefore, the solutions are x = ± √26. There is no need to simplify further as 26 cannot be broken down into a simpler square root. This is a standard approach to solving quadratic equations where the expression is set equal to zero, and it includes finding square roots for the solutions.
