Find all zeros of f(x)= x^3 + 3x^2 − 3x − 1

Mathematics
1 answer:
PSYCHO15rus [73]3 years ago
4 0
F(1) =  1^3 + 3(1)^1 - 3 - 1 = 1 + 3 - 3 - 1 = 0

so one zero  is x = 1, and x-1 is a factor

dividing f(x)  by x - 1 gives x^2 + 4x + 1

x = [-4 +/- sqrt (16 - 4)] /  2

x = -0.27, -3.73

zeroes are 1 , -0.27 and -3.73   Answer

How many real solutions does the equation y2− 8y + 16 = 0 have?
saveliy_v [14]
We can solve this equation by completing the square. Notice that 4*2=8 and 4^{2}=16. Therefore, we can turn y^{2}-8y+16=0 into (y-4)^{2}=0. y, in this equation, only has one real solution: 4. So your answer would be (B).

Answer:

3/-5

Step-by-step explanation:

Rise over Run is what Slope is. So basically we look at it and go how do we get from -6 to -3? Well you add 3, so thats your top number. We look at the bottom of the fractions now. We use the same thought process. How do you get from 14 to 9? Subtract 5. So our slope is 3/-5. Hope this helps

3(d-8) - 5 = 9(d+2) + 1
attashe74 [19]

Answer:

d = - 8

Step-by-step explanation:

3(d-8) - 5 = 9(d+2) + 1

3d-24 - 5 = 9d+18 + 1

3d - 29 = 9d + 19

9d - 3d = -29 - 19

6d = - 48

6d / 6 = -48/6

d = -8
