Choose the correct simplification of the expression −4x2(6x − 5x2 − 5). 20x4 24x3 20x2 −9x4 2x3 − 9x2 20x4 − 24x3 20x2 −20x4 24x3 − 20x2.

20x4−24x3+20x2

Step-by-step explanation:

when simplifying you first distribute the -4x^2. This will result in -24x^3, 20x^4, and 20x^2

20 x^4 - 24 x^3 + 20 x^2 is the only correct answer however not the best simplification.

Step-by-step explanation:

Simplify the following:

-4 x^2 (-5 x^2 + 6 x - 5)

Hint:  Factor a minus sign out of -5 x^2 + 6 x - 5.

Factor -1 out of -5 x^2 + 6 x - 5:

-4 x^2×(-(5 x^2 - 6 x + 5))

Hint:  Multiply -4 and -1 together.

-4 (-1) = 4:

 4 x^2 (5 x^2 - 6 x + 5)

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
