I POSTED THIS OVER TEN TIMES PROBABLY MORE, I REALLY NEED HELP! CAN SOMEONE SOLVE THIS EASY PROBLEM FOR ME PLEASE? I AM HAVING A HARD TIME SOLVING IT, AND NO ONE IS HELPING ME. PLEAS! Complete the problem using the following steps to find the factored form of the polynomial.
1. Find all possible rational roots.
2. Use Descartes' rule of signs to determine the possible number of positive, negative, and
complex roots.
3. Use synthetic division and the quadratic formula to find all roots.
4. Write the polynomial in factored form.
Show ALL work for your steps.

f(x) = x^3 - 4x^2 - 3x + 12

Please help.

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.

the answer is b

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}
