Factor the following trinomial. (Hint: Solve the equations first.)<br><br> x²-2x-2
Alex_Xolod [135]

Answer:

(x-(1+\sqrt{3}))(x-(1-\sqrt{3}))  

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form

ax^{2} +bx+c=0

is equal to

x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}

in this problem we have

x^{2} -2x-2=0  

so

a=1\\b=-2\\c=-2

substitute in the formula

x=\frac{-(-2)(+/-)\sqrt{-2^{2}-4(1)(-2)}} {2(1)}

x=\frac{2(+/-)\sqrt{12}} {2}

x=\frac{2(+/-)2\sqrt{3}} {2}

x_1=\frac{2(+)2\sqrt{3}} {2}=1+\sqrt{3}

x_2=\frac{2(-)2\sqrt{3}} {2}=1-\sqrt{3}

therefore

x^{2} -2x-2=(x-(1+\sqrt{3}))(x-(1-\sqrt{3}))

Kendra sold 200 shares through her broker in June 8. The price per share was $22.10. The broker charged her a 0.5% commission on
MrRa [10]

Answer:

A. $4397.9

Step-by-step explanation:

<em>We are given that Kendra sold 200 shares and that the price per share was $22.1 </em>

<em> </em>

<em>This means that: </em>

<em> </em>

<em>Total value = 200 * 22.1 = $4420 </em>

<em> </em>

<em>Now, we know that the broker charged 0.5% commission on the total value </em>

<em> </em>

<em>This means that: </em>

<em> </em>

<em>Broker's charge = 0.5% * 4420 = 0.005 * 4420 = $22.1 </em>

<em> </em>

<em>Therefore, </em>

<em> </em>

<em>Kendra's return = Total value - broker's charge </em>

<em> </em>

<em>Kendra's return = 4420 - 22.1 = $4397.9 </em>

<em> </em>

<em>Hope this helps :)</em>
