The answer is the answer is C and F.
This is found by inserting the equation above into the quadratic formula or -b plus or minus the square root of b^2 - 4ac over 2a.
With that, you find that the first number is a -3, which eliminates choices B and D.
Then, solving the 4ac portion, you find that inside the square root the number is 29, which gives you the last two answer choices.
Hope this helps!
Answer: If the quadratic equation has real, rational solutions, the quickest way to solve it is often to factorise into the form (px + q)(mx + n), where m, n, p and q are integers. This is especially true where the coefficient of x2 is 1.
Example 1 - Solve x2+7x+12=0
Step-by-step explanation:
that's the only one I remember
Answer:
Step-by-step explanation:
it is 17/50 or 34%
First you had to switch sides of equation.

Then you divide by two from both sides of equation form.

Simplify.

Next, subtract by i from both sides of equation form.

Finally, simplify by equation.

Answer:
Step-by-step explanation: First you would do this 1260.90 divided by 6 = 210. So then you would multiply 210 x 2 = 420. $420 is how much the people who are staying for 6 days. Then since we know it’s $210 per day, we would subtract $420 from 1260.90 and we would get 840.90. Divide that by 6 and get 140. 140 is how much those two people are paying for 2 nights.
