Answer:
<h3>(x + 4) [(x + 4) - (x - 2)]</h3>
Step-by-step explanation:
![(x+4)^2-(x-2)(x+4)=\boxed{(x+4)}(x+4)-(x-2)\boxed{(x+4)}\\\\=\boxed{(x+4)}[(x+4)-(x-2)]](https://tex.z-dn.net/?f=%28x%2B4%29%5E2-%28x-2%29%28x%2B4%29%3D%5Cboxed%7B%28x%2B4%29%7D%28x%2B4%29-%28x-2%29%5Cboxed%7B%28x%2B4%29%7D%5C%5C%5C%5C%3D%5Cboxed%7B%28x%2B4%29%7D%5B%28x%2B4%29-%28x-2%29%5D)
Arrange your given equation to resembles the form
a^2 +2ab+ b^2 because this equals (a+b)^2
So we get:
y^2+16y+8^2=0
Now compare
y^2+16y+8^2 to a^2 +2ab+ b^2
So we got
y^2+2•8 y+8^2=0 which equals (y+8)^2
No. of trees=74
49 more bushes were palnted
hence
74+49=123 bushes
Speed = distance / time
