Give an example of a quadratic with complex roots. Explain how you know it has complex roots.
Vladimir [108]
2x^2 + x + 3=0 has only complex roots.

The determinant is 1-4*2*3 = -23

-23 (or any determinant) is the part under the square root sign,  If that determinant is negative, knowing you cannot take the square root of a negative number, we know the answers must be complex.

Ratling [72]

Answer:

The selling price is $79.53 .

Step-by-step explanation:

Formula

Profit\ percentage = \frac{Profit\times 100}{Cost\ price}

Let us assume that the cost price be x .

As given

Judy Garland Electronics operate on a net-profile rate of 20% on its printer cables.

If the markup is $8.95 and the overhead is $4.31 .

Selling price = Cost price + Markup price + Overhead price

Putting all the values in the above

                   = x + 8.95 + 4.31

                  = x + 13.26

Profit = Selling price - Cost price

         = x + 13.26 - x

         = 13.26

Putting all the values in the above

20 = \frac{13.26\times 100}{x}

x = \frac{13.26\times 100}{20}

x = \frac{1326\times 100}{20\times 100}

x = \frac{1326}{20}

x = $ 66.3

Thus

Selling price = x + 13.26

                    = 66.3 + 13.26

                    = $ 79.53

Therefore the selling price is $79.53 .
