Answers:
- C) x = plus/minus 11
- B) No real solutions
- C) Two solutions
- A) One solution
- The value <u> 18 </u> goes in the first blank. The value <u> 17 </u> goes in the second blank.
========================================================
Explanations:
- Note how (11)^2 = (11)*(11) = 121 and also (-11)^2 = (-11)*(-11) = 121. The two negatives multiply to a positive. So that's why the solution is x = plus/minus 11. The plus minus breaks down into the two equations x = 11 or x = -11.
- There are no real solutions here because the left hand side can never be negative, no matter what real number you pick for x. As mentioned in problem 1, squaring -11 leads to a positive number 121. The same idea applies here as well.
- The two solutions are x = 0 and x = -2. We set each factor equal to zero through the zero product property. Then we solve each equation for x. The x+2 = 0 leads to x = -2.
- We use the zero product property here as well. We have a repeated factor, so we're only solving one equation and that is x-3 = 0 which leads to x = 3. The only root is x = 3.
- Apply the FOIL rule on (x+1)(x+17) to end up with x^2+17x+1x+17 which simplifies fully to x^2+18x+17. The middle x coefficient is 18, while the constant term is 17.
Answer:
Option C. negative
Step-by-step explanation:
we know that
In a quadratic equation of the form
The discriminant is equal to
If D=0 ----> then the system has only one real solution
If D > 0 ---> the the system has two real solutions
If D < 0 ---> then the system has complex solutions
The quadratic equation of the graph has complex solutions
therefore
The discriminant is negative
Points A, B, and E are collinear. They are all on the same line. Don't let the dashed line mislead you, it's just trying to show you that the line goes through the plane. I hope this was helpful.

Hey You!
Subtract the blue beads from the green to solve:
245 - 182 = 63
So, Cameron bought 63 more grams of green beads than blue beads.
