Can somebody check my answers on my quadratic equation? 10 pts!!!?

Your answers are correct!

a million) enable the variety be x reciprocal of this variety a million/x x exceeds 4times a million/x by3 x= 4/x+3 x^2= 4+3x x^2- 3x-4=0 x^2- 4x+x-4=0 x(x-4)+a million(x-4)=0 (x+a million)(x-4)=0 x =4,-a million 2)velocity = distance/time velocity * time = distance enable the time taken to holiday a 40km be x whilst velocity is two km/h difference between time is 1hour 2*x =40 x=40/2 x=20 so the time taken to holiday 40 km at a velocity of two km/hr is 20 hrs the differernce in time is a million hour, so the time is 20hr -a million hr this is nineteen hrs so the comparable distance of 40 km in 19hrs velocity is = 40/19 velocity = 2.a hundred and five km/hr

x^2 + 4x + 2 = 0

x^2 + 4x = -2

(x-2)^2 + 4 = -2

(x-2)^2 = -6

and so on
