If x = 0 then 0^2 +25 = (0+5)(0+5)

The right side of equation: (x+5) * (x+5) = x*x + x*5 + 5*x + 5*5 = x² + 10x + 25 => (x+5) * (x+5) ≠ x² + 25 The solution(s): x² + 25 = (x+5) * (x+5) x² + 25 = x² + 10x + 25 0 = 10x x = 0

x^2 + 25 IS NOT EQUAL TO (x + 5) x (x + 5) = x^2 + 10x + 25

x² + 25 doesn t equal (x+5)(x + 5) That would be x² + 10x + 25
