when describing square and x thing (idk what it's called), l=left r=right t=top b=bottom
3. a= 1 b=8 c=16
square:
tl=x^2
tr=4x
bl=4x
br= 16
criss cross thing:
t=16
l=4
b=8
r=4
answer= (x+4)^2
ex 4:
a= 1 b=-7 c=-30
square:
tl=x^2
tr= 3x
bl= -10x
br= -30
criss cross thing:
t=-30
l= 3
b= -10
r=-7
answer= (x+3) (x-10)
ex 5:
a= 1 b=-1 c=-30
square:
tl=x^2
tr=5x
bl=-6x
br= -30
criss cross thing:
t=-30
l=5
b=-1
r=-6
answer= (x+5) (x-6)

answer:
i think the answer is
1.create another line that intersects the segment.
step-by-step explanation:
this is because, when ever everyone writes when they want to do another part they draw a line threw the middle of the page and write under it.
everyone might not do that, but most people i know do.
for sharing, i hope i was .
