We know that the major axis of the ellipse is 12 ( 2 a = 12 ).An ellipse is a curve with 2 focal points, such that the sum of the distances to the 2 focal points is constant for every point on a curve.If P is a point on a curve:PF 1 + PF 2 = 2 a( Blue line ) + ( Red line ) = 2 a = 12Answer: The sum of the lengths of the red and blue line segments is 12.

Hello,

I)
1 solution with multiplicity 2
(2x+1)²=0

II) ANSWER C (-4.41, -1.59)
-3-√2 and -3+√2

III)
y=x²+2x
y=3x+20
==>x²+2x=3x+20
==>x²-x-20=

Δ=1+4*20=81=9²

(x=(1-9)/2=-4 and y= 3*(-4)+20=8 ) or (x=(1+9)/2=5 and y=3*5+20=35)
