Solve 4x² - 25 = 0 — x = 5/2 or x = -5/2

Problem

$4x^2 - 25 = 0$

Step-by-step solution

فرق مربعین کے طور پر پہچانیں: $4x^2 = (2x)^2$ , $25 = 5^2$ ۔
فیکٹر کریں: $(2x - 5)(2x + 5) = 0$ ۔
حل کریں: $x = \tfrac{5}{2}$ یا $x = -\tfrac{5}{2}$ ۔

Answer

$x = \tfrac{5}{2} \quad \text{or} \quad x = -\tfrac{5}{2}$
