4)
In the graph we can see that the graph intersects the x axis at -5 & 1
So x = -5 or x= 1
Hence
x +5 = 0 or x -1 = 0
Multiplying them we get
(x+5)(x-1) are the correct factors
Option C) is the right answer
5)
We have
x² - 10x + 24=0
We need two numbers which add to give -10 & multiply to give 24.
The numbers are -6 & -4
We split the term -10x
We get
x² -6x-4x+24=0
x(x-6)-4(x-6)=0
(x-6)(x-4)=0
Using Zero Product rule
x-6 = 0 or x-4=0
x = 6 or x = 4
Option C) is the right answer.
4 is the number of respresentation of point A ;)
