Here is the graph of y = x2 - 4x + 3
a) Write down the coordinates
of the turning point on the
graph of y = x2 - 4x + 3 (1)
(
2
-2
a
b) Use the graph to find the roots
of the equation y = x2 - 4x + 3
x
(2)
2
B
-2

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
