Quadratic eq standard form is
Ax^2+bx+c=0
<span>a, b and c are known values.
a can't be 0.</span><span>"x" is the variable
lets take an example
</span><span>x^2 − 4x+2 = 0
</span><span>
x^2-2x-2x+2=0
x(x-2) - 1(x-2)=0
x=1,2

Answer:
Distance between the observer and the red car is 
Step-by-step explanation:
Diameter of field = 500 m
Radius of field =
Let R be the radius and the speed at which the car completes race be w
So,
Car finished 5 laps in minutes = 30
Car finished 1 lap in minutes = 
So, 
Refer the attached figure
Angle between car and observer = wt
So, Distance between the observer and the red car is give as A sin wt
So, Distance between the observer and the red car=
The answer is d but I don’t for sure it might be a or c or b
