Complete the square leave your answer in root form. 2x² - 6x - 3 = 0

x = 1.5 + √3.75   ; x = 1.5 - √3.75

Step-by-step explanation:

2x² - 6x -3 = 0

Add 3 to both sides

2x² - 6x = 3

Divide the entire equation by the coefficient of x²

x² - 3x = 1.5

Divide the coefficient of x by 2 and then square it and add to both sides.

3/2 = 1.5

1.5² = 2.25

Add 2.25 to both sides

x² - 3x + 2.25 = 1.5+2.25

(x - 1.5)² = 3.75

Take square root,

x - 1.5 = ±√3.75

x = 1.5 ± √3.75

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
