Don't try anything positive.
f(-1) = 3 - 4 + 13 - 16 + 4 = 0 This one works so one factor is (x + 1)
f(-1/3) = gives a 0. So another factor is 3x + 1
The last factor is found by dividing 3x^2 + 4x + 1 into the original equation. That's (3x + 1)(x + 1) expanded.
When you do that you find that the last factor is (x^2 + 1)

Answer:
The length of the square is 10 meters.
Step-by-step explanation:
First, you need to know that a square has four equal sides, and that finding the area of a square means multiplying one side by another side. This means that if you know the area of the square, all you have to do is find the square root of the area to find a side length. So, by using a calculator, you can find that the square root of 100 is 10, which is the length of one side of the square.
Answer:
The Camera will drop in 5 seconds
Step-by-step explanation:
1. y=-16t²+400
2. add -16t² to both sides
3. -16t²=-400
4. divide both sides by 16
5. t²=-25
6. t=√25
7. t=5
Answer:
