The solution (s) of x²= 64 can be written as
Answer (1)
The equation x² = 64 is a quadratic equation. To solve for x, we need to find the square root of both sides of the equation. The square root of 64 is 8, but since we are squaring x, the answer can be either positive or negative. Therefore, the solutions are x = 8 and x = -8. - Quadratic Equation: A quadratic equation is an equation of the form ax² + bx + c = 0, where a, b, and c are constants and a ≠ 0.- Square Root: The square root of a number is a value that, when multiplied by itself, equals the original number. For example, the square root of 9 is 3 because 3 × 3 = 9.- Positive and Negative Solutions: When solving for a variable that is squared, there are always two possible solutions: one positive and one negative. This is because squaring a positive or negative number results in a positive number. hope you understand it
