Use the factor theorem to determine where h(x)=x+2 is a factor of f(x)=x^3-3x^2-4x-12? Yes or no

Step-by-step explanation:

x+2=0

x=-2

h(-2)=(-2)³-3(-2)²-4(-2)-12

=-8-12+8-12

=-24≠0

so x=2 is not a factor.

B. No its is not a factor

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
