t⁴ - 16 = (t²)² - 4² = (t² - 4)(t² + 4) = (t - 2)(t + 2)(t² + 4)

(t² + 4)(t + 2)(t - 2)

Explanation

For x² - 4x + m to be a complete square, it must match (x - a)² = x² - 2ax + a²  

Compare: -2a = -4 → a = 2  

So m = a² = 2² = 4  

Check: x² - 4x + 4 = (x - 2)²

Rate = distance / time  

Distance = 500 m = 0.5 km  

Time = 50 min = 50/60 hr = 5/6 hr  

Speed = 0.5 ÷ (5/6) = 0.5 × 6/5 = 3/5 = 0.6 km/hr
