Answer:

The $100 coupon is a better deal.

Step-by-step explanation:

$479.99 - 100 = $379.99

$479.99 x .20 = $95.998

$479.99 - 95.998 = $383.99

What are the zeros of the quadratic function f(x) = 2x2 + 8x – 3? x = –2 – StartRoot StartFraction 11 Over 2 EndFraction EndRoot
Phantasy [73]

Answer:

The zeros are

x=-2+\frac{\sqrt{22}}{2}

x=-2-\frac{\sqrt{22}}{2}  

Step-by-step explanation:

we have

f(x)=2x^{2}+8x-3

we know that

The formula to solve a quadratic equation of the form

ax^{2} +bx+c=0

is equal to

x=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}

in this problem we have

Equate the function to zero

2x^{2} +8x-3=0  

so

a=2\\b=8\\c=-3

substitute in the formula      

x=\frac{-8\pm\sqrt{8^{2}-4(2)(-3)}} {2(2)}  

x=\frac{-8\pm\sqrt{88}} {4} 

x=\frac{-8\pm2\sqrt{22}} {4} 

x=-2\pm\frac{\sqrt{22}}{2}

therefore

x=-2+\frac{\sqrt{22}}{2}

x=-2-\frac{\sqrt{22}}{2}
