Δ = (8i)^2 - 4*(-25) => Δ = -36 +100 => Δ = 64 => x1 =(-8i + 8)/2 => x1 = -4i +4;
x2 = (-8i - 8)/2 => x2 = -4i-4; in this case, your solutions are complex conjugates.

Zepler [3.9K]

Answer:

The distance between house to work is 13 miles .

Step-by-step explanation:

Given as :

The distance that man travel to north = OA = 5 miles

Now, From north ,man turn right and travel to east

So, The distance that man travel to east = AB = 12 miles

Let The distance between house to work = x miles

So, x miles is the displacement from north to east direction

i.e x = $\sqrt{OA^{2} + AB^{2} }$

Or, x = $\sqrt{5^{2} + 14^{2} }$

Or, x = $\sqrt{169 }$

∴ x = 13

So, The distance between house to work = x = 13 miles

Hence, The distance between house to work is 13 miles . Answer
