What is the complete factorization of 108x^2-99y+3

1 answer:

6 0

The quadratic formula would "do" this nicely. a=108; b= -99 and c=3.

Then:
99 plus or minus sqrt(99^2 - 4(108)(3)
x = -----------------------------------------------------
2(108).

Please do the indicated calculations. You should get 2 roots. Now, just supposing that x = 2 were a root (it's not one), then the associated factor would be x-2. Do the same thing with the 2 roots you've just found.

Which shows the correct substitution of the values ab and c from the equation 0 = - 3x ^ 2 - 2x + 6 into the quadrati formula?

scZoUnD [109]

The answer would look something like this:

$\frac{2+-\sqrt{2^{2}-4(-3)(6) }}{2(-3)}$

There could also have a simplified version.

I hope this helps.

The formula v=√64h can be used to find the velocity v in feet per second of an object that has fallen h feet. Find the velocity

zhuklara [117]

Answer:

B) 43.82 feet/sec

Step-by-step explanation:

Fill in the number and evaluate:

v = √(64×30) = √1920 ≈ 43.82 . . . . ft/s

_____

Of course, √(64h) can be simplified to 8√h. You know that √30 lies between 5 and 6, so the velocity lies between 8·5 = 40 and 8·6 = 48. There is only one answer choice in that range.
