Method: الفرق بين مربعين. Verified step-by-step solution with our free AI math solver.

Problem

$x^2 - 25 = 0$

Step-by-step solution

تعرّف عليه كفرق بين مربعين حيث $a = x$ ، $b = 5$ .
طبّق $a^2 - b^2 = (a-b)(a+b)$ : $(x - 5)(x + 5) = 0$ .
اجعل كل عامل يساوي صفرًا: $x = 5$ أو $x = -5$ .

Answer

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