<h2>Good morning,</h2>

<em><u>Answer</u></em>:

The quadratic equation is :  x²+x+1=0

<u><em>Step-by-step explanation:</em></u>

Generally:

let S be the sum of the roots z₁ and z₂

and P be the product of the roots z₁ and z₂

then z₁ and z₂ are the solutions for the equation:  x² − Sx + P = 0

Now,

S=-1 and P=1 then the equation is x²+x+1=0.

Mr. Stanton bought 2.6 yards of fabric for $8.94. About how much was the cost per yard?
lapo4ka [179]

In order to find CPU (Cost per unit) we must take the cost, and divide it by the number of units.

So,

\$8.94\div2.6=\$3.4384

Since we are talking about money, it is implied to round to the nearest cent, so the final answer is

$3.44
