4(10x4 + 3)(10x4 - 3)
x cubed minus 216
It is: (x-y)4
(x2 + 1)(x2 - 2)
x^2(x - 4)(x + 4)
3 dB is a change in power by a factor of 2. If it is plus, i.e. +3dB, power is doubled. If it is minus, i.e. -3dB, power is halved. 6 dB, then is a factor of four, or quarter; 6 dB is a factor of eight, or eighth, etc. The actual equation is 3 log2 (POWER OUT / POWER IN).
which of the following is a factor of x2 - 5x - 6
(x - 2)(x + 2)(x2 - 2x + 4)(x2 + 2x + 4)
2x to the fourth power minus 162 equals -146
No.
