Answer:
Move all terms to the left side and set equal to zero. Then set each factor equal to zero.
Exact Form:
x=1+√5 ,1−√5
This can be also written as y=-2x+2
First of all the - at the beginning = reflection across the x axis.
Then the first 2 is a vertical stretch of 2
the second 2 is a translation of 2 units up.
So
1.ref. across the x axis
2.vert. stretch of 2
3. translation of 2 units up
(2,1) and (3,6)
Slope = (6-1)/(3-2) = 5
y = mx + c
y = 5x + c
at point (2,1)
1 = 5(2) + c
1 = 10 + c
c = -9
y = 5x - 9
