Check if the following equality is true for all values of variables:

(1–2b)(1–5b+b^2 )+(2b–1)(1–6b+b^2 )=b(1–2b)
find:

the expanded form of the left − hand side is

the expanded form of the right − hand side is

so the equality(is/is not) true for all values of the variable.

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

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
