The first three steps of completing the square to solve a quadratic equation x^2+ 8x+0=0are shown below what are the next three steps

Step-by-step explanation:

x^2 + 8x + 0 = 0

Completing the square just means getting yourself a perfect square trinomial on the left side of your equation. It makes factoring easier for you. The steps are like this:

x² + 8x + 0 = 0 ... take the middle coefficient, 8, divide it by 2, and square it. Same process every time. Divide middle by two, square it. This gives you the "perfect square" of your equation. In this case, 8/2 = 4, and 4² = 16. So what you do is add 16 to BOTH sides of the equation.

x² + 8x + 16 = 16 ... factor the left side

(x + 4)(x + 4) = 16 ... notice that your two factors on the left are identical

(x + 4)² = 16 ... now we want to solve for x. Start by taking the square root of both sides

x + 4 = √16 ... √16 can give us two results: -4 and 4. So solve for both.

x + 4 = 4         x + 4 = -4  ... solve for x

x = 0,              x = -8

answer:     true

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
