Answer:
Ahmed is 7 , his father is 49
Explanation:
given Ahmed is x years old and his father is x² years old
the sum of their ages is 56 , that is
x² + x = 56 ( subtract 56 from both sides )
x² + x - 56 = 0 ← quadratic equation in standard form
(x + 8)(x - 7) = 0 ← in factored form
equate each factor to zero and solve for x
x + 8 = 0 ⇒ x = - 8
x - 7 = 0 ⇒ x = 7
since x > 0 , then x = 7
Ahmed is 7 years old and his father is 7² = 49 years old
