how to solve x^2 +400x + 960000 such large quadratic equations

1.	how to solve x^2 +400x + 960000 such large quadratic equations
Answer» Splitting the middle term X2. + 400x - 960000X2 + ( 1200x - 800x) + ( 1200 × 800)x ( x + 1200) - 800 ( x + 1200)(x + 1200)(x - 800) First findb2-4ac=400*400-4(960000)=160000-3840000= negativeSo the solution of this equation is not possible Take it 10^n for that Use quadratic formula or completing the square
