Answer:

x = -1.5, -1, 2.

Step-by-step explanation:

I am assuming you want to solve this>

Solve 2x ³ + x ² -7x - 6​ = 0

It looks like x = -1 is a solution so we try it:

2*(-1)^3 + (-1)^2 -7(-1) - 6

= -2 + 1 + 7 - 6

= -1 + 1 = 0

So x = -1 is one root.

So (x + 1) must be a factor of P(x)

Now we divide by x + 1:

x + 1)2x ³     + x ²   -7x -  6​( 2x^2 - x - 6  <--- quotient

       2x^3 + 2x^2

                  -x^2  - 7x

                  -x^2  -  x

                             -6x -  6

                             -6x -  6

                              ----------

2x^2 - x - 6 = 0

(2x + 3)(x - 2) = 0

x = -1.5, 2.

When the denominators of the numerator and denominator of a complex fraction are the same, the result is the ratio of the numerators. Here, that ratio can be reduced, since both numbers are even.

Answer:

  $1800

Step-by-step explanation:

The tax due is ...

  3% × $10,000 + 5% × ($40,000 -10,000)

  = 5% × $40,000 - (5% -3%)($10,000)

  = $2000 - 200

  = $1800 . . . . tax due

_____

<em>Additional comment</em>

The table is structured so you need to compute the amount due in each bracket and add those to find the total due.

I prefer to compute the tax due by applying the appropriate tax rate to the whole amount, then subtracting a "discount" that reflects the fact that the rate doesn't actually apply to the whole amount.
