...whars the figure??? You did give us dimensions but not the figure..
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.
Range should be (-∞ , 10]
answer is C.
No don’t stab yourself! But I really hope someone helps you with this, I would but I just don’t understand sorry
Answer:
2x*x
2x*-5
1*x
1*-5
2x²-10x+x-10 add numbers that have similar variables
-2x²-10x+x-10
=[-2x²-9x-10]
