Answer:

A

Step-by-step explanation:

Note: I suppose you typed the question wrong, thus I calculated the question in the picture

x =  \frac{ - b +  -  \sqrt{{b}^{2}  - 4ac}  }{2}  \\  =  \frac{5 +  -  \sqrt{25 - 4 \times  - 2 \times 1} }{2}  \\  =  \frac{5 +  -  \sqrt{25  + 8} }{2}  \\  =  \frac{5  +  -  \sqrt{33} }{2}

Inga [223]

If <em>x</em> = 4.338338338…, then

and subtracting <em>x</em> from this eliminate the trailing decimal.

1000<em>x</em> - <em>x</em> = 4338.338338338… - 4.338338338…

999<em>x</em> = 4334

<em>x</em> = 4334/999
