  The initial product will have mn terms, but simplification my reduce that number to as few as one or two terms.

Step-by-step explanation:

We have to assume each polynomial is in standard form. Each of the m terms of the first polynomial will be multiplied by each of the n terms of the second, so there will be a total of m×n terms resulting from the initial multiplication.

Some of those terms may be combined when the sum is simplified, so the end result may have as few as 1 or 2 terms.

Examples:

1. 2 × b = 2b . . . . . each has 1 term; the result has 1 term.

2. (x -a)(x +a) = x² -ax +ax -a² (2×2=4 terms) = x² -a² . . . . the result has 2 terms.

3. (x -a)(x³ +x) = x⁴ -ax³ +x² -ax . . . the result has 2×2 = 4 terms

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
