Answer:
-1 and -2
Step-by-step explanation:
f(x) = 4x² − 8kx + 8x −9
f(x) = 4x² − 8(k−1)x − 9
If one root of f(x) is the opposite of the other, then f(x) must be a difference of squares, which means -8(k−1) = 0.
-8(k−1) = 0
k = 1
Therefore, the other polynomial is:
x² + 3x + 2
(x + 1) (x + 2)
The zeros are -1 and -2.
Answer: The correct answer is Choice C.
Step-by-step explanation: The drama club raised 150% of their goal, which is represented by choice c.
The proper way to calculate this percentage is to calculate how much they earned over the goal. They earned $150 over a goal of $300, so you divide 150 by 300 to determine the percentage.
150/300 = .5, or 50%
So, they earned 100% (300) plus 50% (150), for a total of 150% of the goal.
