Write the following equation set equal to zero and in factored form. (x - 2)(x - 3) = 2 (x - 1)(x - 4) = 0 (x - 2)(x - 3) = 0 (x - 4)(x - 5) = 0

i dont get it. where are the "descriptions"?

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3

you,

mrb

1/800 is the right answer
