The number of solutions of a quadratic equation

ax^2+bx+c=0

Depends on its discriminant

/Delta=b^2-4ac

If /Delta>0 there are two distinct solutions

If /Delta=0 there are two coincident solutions

If /Delta<0 there are no solutions.

We know that there are two real solutions (I assume you mean distinct solutions), so we know that the discriminant is positive:

a line segment has (x1,y1) as one endpoint and (xm,ym) as its midpoint. Find the other endpoint (x2,y2)of the line segment in te
svlad2 [7]

(x1,y1)

(x2,y2)

(xm,ym)

Midpoint formula is given as below.

((x1 + x2)/2 , (y1 + y2)/2 )

Where

(x1 + x2)/2 = xm ----------- (1)

(y1 + y2)/2 = ym ----------- (2)

Equation (1) implies that;

x1 + x2 = 2xm

x2 = 2xm – x1

Equation (2) implies that;

y1 + y2 = 2ym

y2 = 2ym – y1

Thus the end point is

<span>(x2,y2) = (2xm – x1, 2ym – y1)</span>
