Answer:

  2x^2 -x +1 = 0

Step-by-step explanation:

For roots α and β, the original equation can be factored as ...

  f(x) = 2(x -α)(x -β)

If we add 1 to each of those roots, the factors become ...

  g(x) = 2(x -(α+1))(x -(β+1))

This can be rearranged to be ...

  g(x) = 2((x -1) -α)((x -1) -β)

That is, we can get the desired equation by replacing x with x-1, effectively shifting the function right one unit.

  2(x -1)² +3(x -1) +2 = 0

  2x^2 -x +1 = 0

Your friend buys a skateboard that is on sale for one third off the original price. Your friend spent $36 than the original pric
White raven [17]

Answer:

original price of skateboard = $54

Step-by-step explanation:

Let the original price of the skateboard be x

selling price = one third off the original price = $36

x - (1/3x) = 36

\frac{x}{1} - \frac{x}{3} = \frac{3x-x}{3} = \frac{2x}{3}

\frac{2x}{3} = 36\\2x = 108\\x = \frac{108}{2} = 54

∴ x = 54
