This one is so easy that your brain refuses to accept it.
It's looking for a harder answer, but can't find it !
You're totally correct, as far you went. x² + 2x does = -1
Now add ' 1 ' to each side: x² + 2x + 1 = 0
Can you factor that quadratic ?
Can you mash it through the quadratic formula ?
Actually, it's the simplest possible perfect square.
x² + 2x + 1 = (x + 1)²
So the solutions of x² + 2x + 1 = 0 are both x = -1 .
Don't say anything.
I know it's embarrassing.
You need k by itself, so the only way to do that is to divide both sides by 5
Answer:
It's A

I hope that it's a correct answer.
The correct answer is 720 I did this problem long time ago hope this helps :)
Yes. Parallel means same slope as original line. So it’s 2
