G^5 -g = g(g^4 -1)=g(g^2 -1)(g^2 +1) = g(g-1)(g+1)(g^2 +1)
24g^2 -6g^4 = 6g^2(4 -g^2) = 6g^2(2 -g)(2 +g)
It’s CD because it’s a longer line
<h3>Slopes of perpendicular lines.</h3>
Let k: y = a₁x + b₁ and l: y = a₂x + b₂. Then
<h3>k ║ l ⇔ a₁ = a₂</h3><h3>k ⊥ l ⇔ a₁ · a₂ = -1</h3>
We have the line y = -x + 5 ⇒ a₁ = -1.
Therefore
a₂ · (-1) = -1
-a₂ = -1 I<em>change the signs</em>
<h2>a₂ = 1</h2>
