Answer: C) Find the factors of c that add up to b.
==============================================
Explanation:
If we want to factor something in the form x^2+bx+c, then we look for two numbers that
-------------
Let's look at a specific example
Consider factoring x^2+5x+6
We need to find two numbers that...
- Multiply to c = 6
- Add to b = 5
Through trial and error, you should find the two numbers to be 3 and 2. This means it factors to (x+3)(x+2). The order of the factors doesn't matter.
You can use the FOIL rule or the box method to expand out (x+3)(x+2). You should get x^2+5x+6 again.
Answer:
its 3rd graph, the one with (-1,0) point
Find the standard form of the equation of the parabola with a focus at (-4, 0) and a directrix at x = 4.
43 can fit into 93 two whole times.
After that, there's only room for another 7 inside the 93,
so there's no way to stuff the whole 43 in there again.
