Answer:
Step-by-step explanation:
The solution set of the equation 4x² - 25 = 0 is {±2.5}.
The given equation is a quadratic equation of the form ax² + bx + c = 0, where a = 4, b = 0, and c = -25. To find the solution set, we can use the quadratic formula:
x = (-b ± √(b² - 4ac)) / (2a)
Plugging in the values, we have:
x = (-0 ± √(0² - 4(4)(-25))) / (2(4))
Simplifying further, we have:
x = (±√(0 + 400)) / 8
x = ±√(400) / 8
x = ±20 / 8
Hence, the solution set of the equation is {±2.5}.
