Expand (x+2)^2: x^2 + 4x + 4 : remember that (a+b)^2 = a^2 + 2ab + b^2
So: x^2 + 4x + 4 - x^2 = 60

Answer:

(x-10) (x+1) =0

x=10                     x=-1

Step-by-step explanation:

x^2 -9x-10 =0

Factor

What two numbers multiply to -10 and add to -9

-10*1 = -10

-10+1=-9

(x-10) (x+1) =0

Using the zero product property

x-10 = 0             x+1=0

x-10+10=0+10       x+1-1=0-1

x=10                     x=-1

These are the x intercepts

Ok. This is called a Coordinate Plane (aka line plots). Your teacher is asking to find the number on those plots.
You have your X and Y axis.
You go over to X before going to Y
So I work my way up so your first one is
1,2
Second is
-2,4
Third is
2,6
and the last one (the top plot)
1,8

Hope this helped!
Brainiest please!
