Select the polynomial that is a perfect square trinomial. Group of answer choices

x2 + 20x + 100

x2 + 8x + 64

x2 + 10x + 50

x2 + 21x + 49

first option

Step-by-step explanation:

A perfect square trinomial in the list is

x² + 20x + 100

= (x + 10)(x + 10)

= (x + 10)² ← a perfect square

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
