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:
660
Step-by-step explanation:
If n represents the number, we are told ...
900% × n = 5940
We know that 900% = 900/100 = 9, so this is ...
9n = 5940
Dividing by the coefficient of n gives ...
n = 5940/9 = 660
The number is 660.
