f(x) is a quadratic polynomial, with roots represented by, α and β, where the both the sum and product of the roots are equal. For what real value of α or β, will f(x) always be undefined?

Bonjour! donc si je suis tout à fait honnête... je ne sais pas vraiment désolé j'espère que vous trouverez votre réponse bye-bye!

Step-by-step explanation:

a+b=ab

a=b/(b-1)

b=a/(a-1)

to make a number undefined make the denominator equal to zero. so just make b-1=0 and a-1=0 so to make the polynomial f(x) undefined, b has to be 1 and a needs to be 1.

Hope this helps :)

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
